# Air Quality Sensor 3D Printed Enclosure ## Overview https://youtu.be/6KpKyPQaUaE ## IOT Air Sensor Monitor Build a 3D printed enclosure for your IOT Air Quality Sensor. This project [is similar to our other air quality sensor guide](https://learn.adafruit.com/diy-air-quality-monitor), except it uses Adafruit STEMMA sensors and _has minimal soldering required_.   ![sensors_iphone-hero.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/792/medium640/sensors_iphone-hero.jpg?1604601153) This project uses sensors to **measure PM2.5 (particles that are 2.5 microns or smaller in diameter) dust concentrations, temperature and humidity**.  This weatherproof enclosure is modeled after a silo-home. We've included different types of mounting holes and brackets for different mounting configurations. ## Adafruit IO Build an [Adafruit IO](https://io.adafruit.com/welcome) Dashboard to visualize your air quality sensor's data at a glance. [Adafruit IO](https://io.adafruit.com/welcome) is free and includes up to 30 days of storage for your sensor's data.  You can view and interact with this data from anywhere in the world with a wireless connection. ![sensors_hero-aio.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/803/medium640/sensors_hero-aio.jpg?1604606811) ## Enclosure Design The case is themed to resemble a modern silo grain bin house. The roof is removable by unscrewing the top from the case. The Feather boards are securely mounted inside via heat set inserts. A mounting plate is used to secure the enclosure to a surface. Weatherproof cable gland is used to keep moisture out. The bottom cover is modular allowing for a different set of sensors. ![sensors_hero-case-open.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/793/medium640/sensors_hero-case-open.jpg?1604601456) ## Choose Your Sensors The enclosure and code accommodate for two different sets of sensors.

This diagram was created using the software package [Fritzing](http://fritzing.org/download/). ## Adafruit Library for Fritzing Use Adafruit's Fritzing parts library to create circuit diagrams for your projects. Download the library or just grab individual parts. Get the library and parts from [GitHub - Adafruit Fritzing Parts](https://github.com/adafruit/Fritzing-Library/tree/master/parts). ## Choose Your Sensors This project can use two different sets of sensors. The first set uses the BME280 and the PMS5003. The second set uses the BME680 and the PMSA003i. The wiring is slightly different and noted below. The code accommodates for both setups. ## PMSA003i & BME680 ![](https://cdn-learn.adafruit.com/assets/assets/000/096/695/medium800/sensors_pmsa3i_bb.png?1604346717) **Make the following connections between the BME680 and the FeatherWing:** - **Board 3V**  to  **sensor VIN** - **Board GND**  to  **sensor GND** - **Board SCL**  to  **sensor SCL** - **Board SDA**  to  **sensor SDA** **Then, make the following connections between the PMSA003i and the BME680:** - **Sensor VIN ** to ** board 5V** - **Sensor GND ** to ** board GND** - **Sensor SCL** to **board SCL** - **Sensor SDA** to **board SDA** ## PMS5003 & BME280 ![](https://cdn-learn.adafruit.com/assets/assets/000/096/696/medium800/sensors_temperature___humidity_wiring_bb.png?1604346765) **Make the following connections between the BME280 and the FeatherWing:** - **Board 3V**  to  **sensor VIN** - **Board GND**  to  **sensor GND** - **Board SCL**  to  **sensor SCK** - **Board SDA**  to  **sensor SDI** **Then, make the following connections between the PM2.5 adaptor and the FeatherWing:** - **Sensor VCC ** to ** board 5V** - **Sensor GND ** to ** board GND** - **Sensor TX ** to ** board RX** - Remember:  **RX does not connect to RX!** # Air Quality Sensor 3D Printed Enclosure ## Wiring ## Wire for BME280 Use a piece of 4-wire silicone ribbon cable, 15cm (6in) in length. ![sensors_bme280-wire.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/632/medium640/sensors_bme280-wire.jpg?1604328043) ## Wired BME280 Solder the ribbon cable to the pins on the BME280 breakout board. - VIN - GND - SCK - SDI ![sensors_bme280-wiring.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/633/medium640/sensors_bme280-wiring.jpg?1604328067) ## Wiring for PMS5003 Use a piece of 4-wire silicone ribbon cable, 7cm (3in) in length. Solder the wires to the pins on the breakout adapter for the PMS5003. - VCC - GND - TXD - RST ![sensors_psm5003-wired.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/634/medium640/sensors_psm5003-wired.jpg?1604328114) ## Doubler FeatherWing + I2C (BME280 or BME680) Wiring Use the photo and labels to reference the wiring. The BME280 and BME680 use exact same pins on the FeatherWing Doubler. ![sensors_featherwing-wiring.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/635/medium640/sensors_featherwing-wiring.jpg?1604328175) ## Doubler FeatherWing + PMS5003 Wiring Use the photo and labels to reference wiring. The PMS5003 requires dedicated wiring to the Doubler FeatherWing. The PMSA003i plugs directly into the STEMMA port on the BME680, essentially daisy chained I2C. ![sensors_featherwing-pms5003.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/636/medium640/sensors_featherwing-pms5003.jpg?1604328215) ## Feather Headers Install the male 12pin and 16pin headers to the Feather M4 and Airlift FeatherWing. Solder the headers to the pins. ![sensors_feathers-topdown.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/798/medium640/sensors_feathers-topdown.jpg?1604604173) ![sensors_feathers-headers-side.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/799/medium640/sensors_feathers-headers-side.jpg?1604604185) ## Install Feathers to Doubler Line up the male header pins with the female header pins on the FeatherWing Doubler. Press firmly to fully seat the headers. ![sensors_feathers-doubler-preinstall.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/800/medium640/sensors_feathers-doubler-preinstall.jpg?1604604247) ![sensors_feathers-doubler-install.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/801/medium640/sensors_feathers-doubler-install.jpg?1604604273) ## USB micro B Connector Wire up the micro USB b connector to a piece of 4-wire ribbon cable, about 12cm (5in )in length. This is used as the power cable for the Feather. Use the USB extension cable to increase the length of the cable. Do not wire the micro USB connector to the USB extension cable just yet. The USB cable must be installed into the cable gland in the case first before wiring. ![sensors_usb-diy-cable.jpg](https://cdn-learn.adafruit.com/assets/assets/000/096/637/medium640/sensors_usb-diy-cable.jpg?1604328328) # Air Quality Sensor 3D Printed Enclosure ## Adafruit IO Setup ## Obtain Adafruit IO Key You will need your Adafruit IO username and secret API key.

Others are _CircuitPython-ready_, but need to have it installed. As well, you may want to update the version of CircuitPython already installed on your board. The steps are the same for installing and updating.  - To **install (or update) your CircuitPython board**, [follow this page and come back here when you've successfully installed (or updated) CircuitPython.](https://learn.adafruit.com/welcome-to-circuitpython/installing-circuitpython) ## CircuitPython Library Installation First make sure you are running the [latest version of Adafruit CircuitPython](https://github.com/adafruit/circuitpython/releases) for your board. Next you'll need to install the necessary libraries to use the hardware--carefully follow the steps to find and install these libraries from [Adafruit's CircuitPython library bundle](https://github.com/adafruit/Adafruit_CircuitPython_Bundle) matching your version of CircuitPython.  CircuitPython hardware shows up on your computer operating system as a flash drive when connected via usb. The flash drive is called  **CIRCUITPY**  and contains a number of files. You will need to add additional files to enable the features of this project. First, create a folder on the drive named lib if it is not already there. Ensure your board's  **lib**  folder has the following files and folders ** ** copied over. The version of the files must be the same major version as your version of CircuitPython (i.e. 5.x for 5.x, 6.x for 6.x etc.) - **adafruit\_bus\_device** - **adafruit\_esp32spi** - **adafruit\_io** - **adafruit\_logging.mpy** - **adafruit\_requests.mpy** - **adafruit\_pm25** - **neopixel.mpy** - **simpleio.mpy** - **adafruit\_bme280.mpy** # Air Quality Sensor 3D Printed Enclosure ## Internet Connect! # Connect to WiFi OK, now that you have your  **settings.toml** file set up - you can connect to the Internet. To do this, you need to first install a few libraries, into the lib folder on your **CIRCUITPY** drive. Then you need to update **code.py** with the example script. Thankfully, we can do this in one go. In the example below, click the **Download Project Bundle** button below to download the necessary libraries and the **code.py** file in a zip file. Extract the contents of the zip file, open the directory **examples/** and then click on the directory that matches the version of CircuitPython you're using and copy the contents of that directory to your **CIRCUITPY** drive. Your **CIRCUITPY** drive should now look similar to the following image: ![CIRCUITPY](https://adafruit.github.io/Adafruit_CircuitPython_Bundle/esp32spi_esp32spi_simpletest.py.png ) Info: Update to CircuitPython 9.2.x or later to use this example. https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI/blob/main/examples/esp32spi_simpletest.py And save it to your board, with the name **code.py**. Don't forget you'll also need to create the **settings.toml** file as seen above, with your WiFi ssid and password. In a serial console, you should see something like the following. For more information about connecting with a serial console, view the guide [Connecting to the Serial Console](https://learn.adafruit.com/welcome-to-circuitpython/kattni-connecting-to-the-serial-console). ```terminal >>> import wifitest ESP32 SPI webclient test ESP32 found and in idle mode Firmware vers. 1.7.5 MAC addr: 24:C9:DC:BD:0F:3F HomeNetwork RSSI: -46 HomeNetwork RSSI: -76 Fios-12345 RSSI: -92 FiOS-AB123 RSSI: -92 NETGEAR53 RSSI: -93 Connecting to AP... Connected to HomeNetwork RSSI: -45 My IP address is 192.168.1.245 IP lookup adafruit.com: 104.20.39.240 Ping google.com: 30 ms Fetching text from http://wifitest.adafruit.com/testwifi/index.html ---------------------------------------- This is a test of Adafruit WiFi! If you can read this, its working :) ---------------------------------------- Fetching json from http://wifitest.adafruit.com/testwifi/sample.json ---------------------------------------- {'fun': True, 'company': 'Adafruit', 'founded': 2005, 'primes': [2, 3, 5], 'pi': 3.14, 'mixed': [False, None, 3, True, 2.7, 'cheese']} ---------------------------------------- Done! ``` Going over the example above, here's a breakdown of what the program is doing: - Initialize the ESP32 over SPI using the SPI port and 3 control pins: ```python esp32_cs = DigitalInOut(board.ESP_CS) esp32_ready = DigitalInOut(board.ESP_BUSY) esp32_reset = DigitalInOut(board.ESP_RESET) #... else: spi = busio.SPI(board.SCK, board.MOSI, board.MISO) esp = adafruit_esp32spi.ESP_SPIcontrol(spi, esp32_cs, esp32_ready, esp32_reset) ``` - Get the socket pool and the SSL context, and then tell the `adafruit_requests` library about them. ```python pool = adafruit_connection_manager.get_radio_socketpool(esp) ssl_context = adafruit_connection_manager.get_radio_ssl_context(esp) requests = adafruit_requests.Session(pool, ssl_context) ``` - Verify an ESP32 is found, checks the firmware and MAC address ```auto if esp.status == adafruit_esp32spi.WL_IDLE_STATUS: print("ESP32 found and in idle mode") print("Firmware vers.", esp.firmware_version) print("MAC addr:", ":".join("%02X" % byte for byte in esp.MAC_address)) ``` - Perform a scan of all access points it can see and print out the name and signal strength. ```python for ap in esp.scan_networks(): print("\t%-23s RSSI: %d" % (ap.ssid, ap.rssi)) ``` - Connect to the AP we've defined here, then print out the local IP address. Then attempt to do a domain name lookup and ping google.com to check network connectivity. (Note sometimes the ping fails or takes a while; this isn't a big deal.) ```python print("Connecting to AP...") while not esp.is_connected: try: esp.connect_AP(ssid, password) except OSError as e: print("could not connect to AP, retrying: ", e) continue print("Connected to", esp.ap_info.ssid, "\tRSSI:", esp.ap_info.rssi) print("My IP address is", esp.ipv4_address) print( "IP lookup adafruit.com: %s" % esp.pretty_ip(esp.get_host_by_name("adafruit.com")) ) ``` Now we're getting to the really interesting part of the example program. We've written a library for web fetching web data, named [adafruit\_requests](https://github.com/adafruit/Adafruit_CircuitPython_Requests). It is a lot like the regular Python library named [requests](https://requests.readthedocs.io/en/latest/). This library allows you to send HTTP and HTTPS requests easily and provides helpful methods for parsing the response from the server. - Here is the part of the example program is fetching text data from a URL. ```python TEXT_URL = "http://wifitest.adafruit.com/testwifi/index.html" # Further up in the program # ... print("Fetching text from", TEXT_URL) r = requests.get(TEXT_URL) print('-' * 40) print(r.text) print('-' * 40) r.close() ``` - Finally, here the program is fetching some JSON data. The `adafruit_requests` library will parse the JSON into a Python dictionary whose structure is the same as the structure of the JSON. ```auto JSON_URL = "http://wifitest.adafruit.com/testwifi/sample.json" # Further up in the program # ... print("Fetching json from", JSON_URL) r = requests.get(JSON_URL) print('-' * 40) print(r.json()) print('-' * 40) r.close() ``` # Advanced Requests Usage Want to send custom HTTP headers, parse the response as raw bytes, or handle a response's http status code in your CircuitPython code? We've written an example to show advanced usage of the requests module below. To use with CircuitPython, you need to first install a few libraries, into the lib folder on your **CIRCUITPY** drive. Then you need to update **code.py** with the example script. Thankfully, we can do this in one go. In the example below, click the **Download Project Bundle** button below to download the necessary libraries and the **code.py** file in a zip file. Extract the contents of the zip file, open the directory **examples/** and then click on the directory that matches the version of CircuitPython you're using and copy the contents of that directory to your **CIRCUITPY** drive. https://github.com/adafruit/Adafruit_CircuitPython_Requests/blob/main/examples/esp32spi/requests_esp32spi_advanced.py Your **CIRCUITPY** drive should now look similar to the following image: ![CIRCUITPY](https://adafruit.github.io/Adafruit_CircuitPython_Bundle/requests_esp32spi_requests_esp32spi_advanced.py.png ) # WiFi Manager The way the examples above connect to WiFi works but it's a little finicky. Since WiFi is not necessarily so reliable, you may have disconnects and need to reconnect. For more advanced uses, we recommend using the `WiFiManager` class. It will wrap the connection/status/requests loop for you - reconnecting if WiFi drops, resetting the ESP32 if it gets into a bad state, etc. Here's a more advanced example that shows using the `WiFiManager` and also how to fetch the current time from a web source. https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI/blob/main/examples/esp32spi_localtime.py # Further Information For more information on the basics of doing networking in CircuitPython, see this guide: ### Networking in CircuitPython [Networking in CircuitPython](https://learn.adafruit.com/networking-in-circuitpython) # Air Quality Sensor 3D Printed Enclosure ## Code Usage ## Text Editor Adafruit recommends using the Mu editor for editing your CircuitPython code. You can get more info in [this guide](https://learn.adafruit.com/welcome-to-circuitpython/installing-mu-editor). Alternatively, you can use any text editor that saves simple text files. ## Secrets File Setup Open the  **secrets.py ** file on your CircuitPython device using Mu or your favorite text editor. You're going to edit this file to enter your WiFi credentials along with your keys.  - **Change**  `ssid` to  **the name of your WiFi network** - **Change ** `password` to  **your WiFi network's password ** - **Change ** `aio_user` to  **your Adafruit IO Username** - **Change ** `aio_key` to  **your Adafruit IO Key**. ```python secrets = { 'ssid' : 'home ssid', 'password' : 'my password', 'timezone' : "America/New_York", # http://worldtimeapi.org/timezones 'aio_user' : 'MY_ADAFRUIT_IO_USERNAME', 'aio_key' : 'MY_ADAFRUIT_IO_KEY', 'latitude': MY_LAT, # https://www.latlong.net/ 'longitude': MY_LON, 'elevation': MY_ELE } ``` Next, let's to add your location's latitude, longitude and altitude data to the secrets file. Entering your location will allow the Map Block to show an image of your sensor's location. **For privacy reasons, we suggest limiting your location data to your city, town, or municipality**. Instead of setting our sensor's location to Adafruit's exact address, we'll set it to New York City. [Navigate to this website to find your location's GPS latitude, longitude and altitude coordinates](https://www.maps.ie/coordinates.html) and enter your city/town. ![](https://cdn-learn.adafruit.com/assets/assets/000/096/741/medium800/sensors_temperature___humidity_GPS_coordinates_on_Google_Maps___Latitude_Longitude_Search.png?1604507976) In the secrets file, change `MY_LAT`, `MY_LON`, and `MY_ELE` to the values obtained from the website above. ## Code Click the Download: Project Zip File link below in the code window to get a zip file with all the files needed for the project. Copy  **code.py**  from the zip file and place on the  **CIRCUITPY**  drive which appears when your board is plugged into your computer via a known good USB cable. https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Adafruit_IO_Air_Quality/code.py Once all the files are copied from your computer to the Feather, you should have the following files on your  **CIRCUITPY**  drive: ![](https://cdn-learn.adafruit.com/assets/assets/000/096/743/medium800/sensors_lib.png?1604511291) ## Modify Code The **code.py** file is configured for an Air Quality Sensor using a BME280 and PMS5003 sensors. You'll need to open a text editor and make the following modifications in the **code.py** file for the BME680 and PMSA003l. **Change out the following lines** from `uart = busio.UART(board.TX, board.RX, baudrate=9600)` `pm25 = adafruit_pm25.PM25_UART(uart, reset_pin)` to `# uart = busio.UART(board.TX, board.RX, baudrate=9600)` `# pm25 = adafruit_pm25.PM25_UART(uart, reset_pin)` **Change the following line** from `bme_sensor = adafruit_bme280.Adafruit_BME280_I2C(i2c)` to  `# bme_sensor = adafruit_bme280.Adafruit_BME280_I2C(i2c)` Then, **uncomment the following lines** to enable the PMSA003I and BME680 sensors: ```python # Uncomment below for PMSA003I Air Quality Breakout pm25 = adafruit_pm25.PM25_I2C(i2c, reset_pin) # Uncomment below for BME680 import adafruit_bme680 bme_sensor = adafruit_bme680.Adafruit_BME680_I2C(i2c) ``` ## Code Usage Before permanently installing the sensor, you should test the sensor to make sure the sensors are wired correctly and the board can publish data to Adafruit IO. **Plug the sensor into a mini-USB power cable**. and **navigate to the Adafruit IO Dashboard you created earlier**. Every ten minutes all the blocks populate with values. Since the air quality index values are measured in real-time, they may be higher than EPA NowCast real-time AQI values. After a day of the sensor capturing and logging data, the AQI - 1 Day line chart block will display air quality measurements every hour for the previous day. ![](https://cdn-learn.adafruit.com/assets/assets/000/096/742/medium800/sensors_temperature___humidity_IO_-_My_Air_Quality_Sensor.png?1604508207) Note - the BME280 sensor may fluctuate +/- 1 to +/- 2 degrees due to the temperature of the sensor inside the case. # Air Quality Sensor 3D Printed Enclosure ## 3D Printing ## Parts List STL files for 3D printing are oriented to print "as-is" on FDM style machines.
