# No-Code DS18B20 Temperature Sensor with WipperSnapper ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/117/078/medium800/adafruit_io_IMG_8062-special.jpg?1671043939) **One-wire temperature sensors like the DS18B20 can measure temperature with a minimal amount of hardware and wiring.** These sensors use a digital protocol to send accurate temperature readings directly to your development board without the need for an analog-to-digital converter or other extra hardware. You can get one-wire sensors in different form factors like waterproof and high-temperature probes--these are perfect for sensing temperature in many different projects and applications. **With just a few connections and a WipperSnapper device, you'll be sensing temperature in no time!** **This guide explores how to connect a DS18B20 one-wire temperature sensor to a board supported by the WipperSnapper firmware. You'll send its temperature data to be logged by Adafruit IO. All without any code!** ## What is WipperSnapper WipperSnapper is a firmware designed to turn any WiFi-capable board into an Internet-of-Things device without programming a single line of code. WipperSnapper connects to [Adafruit IO](https://io.adafruit.com/), a web platform designed ([by Adafruit!](https://www.adafruit.com/about)) to _display_, _respond_, and _interact_ with your project's data. Simply load the WipperSnapper firmware onto your board, add credentials, and plug it into power. Your board will automatically register itself with your Adafruit IO account. From there, you can add _components_ to your board such as buttons, switches, potentiometers, sensors, and more! Components are _dynamically _added to hardware, so you can immediately start interacting, logging, and streaming the data your projects produce without writing code. ## Parts Featured ### Adafruit ESP32 Feather V2 - 8MB Flash + 2 MB PSRAM [Adafruit ESP32 Feather V2 - 8MB Flash + 2 MB PSRAM](https://www.adafruit.com/product/5400) One of our star Feathers is the [Adafruit HUZZAH32 ESP32 Feather](https://www.adafruit.com/product/3405) - with the fabulous ESP32 WROOM module on there, it makes quick work of WiFi and Bluetooth® projects that take advantage of Espressifs most popular chipset.

There is nothing to "uninstall". However, you may want to "move" your board from running WipperSnapper to running Arduino or CircuitPython. You also may need to restore your board to the state it was shipped to you from the Adafruit factory.  ### Moving from WipperSnapper to CircuitPython Follow the steps on the [Installing CircuitPython page](https://learn.adafruit.com/welcome-to-circuitpython/installing-circuitpython) to install CircuitPython on your board running WipperSnapper. - If you are unable to double-tap the RST button to enter the UF2 bootloader, follow the _"Factory Resetting a WipperSnapper Board"_ instructions below. Uploading this sketch will overwrite WipperSnapper. If you want to re-install WipperSnapper, follow the instructions at the top of this page. ### Moving from WipperSnapper to Arduino If you want to use your board with Arduino, you will use the Arduino IDE to load _any_ sketch onto your board. First, follow the page below to set up your Arduino IDE environment for use with your board. [Setup Arduino IDE](https://learn.adafruit.com/adafruit-esp32-feather-v2/arduino-ide-setup) Then, follow the page below to upload the "Arduino Blink" sketch to your board. [Upload Arduino "Blink" Sketch](https://learn.adafruit.com/adafruit-esp32-feather-v2/blink) Uploading this sketch will overwrite WipperSnapper. If you want to re-install WipperSnapper, follow the instructions at the top of this page. ### Factory Resetting a WipperSnapper Board Sometimes, hardware gets into a state that requires it to be "restored" to the original state it shipped in. If you'd like to get your board back to its original factory state, follow the guide below. [Factory Reset your Adafruit Feather HUZZAH ESP32-V2](https://learn.adafruit.com/adafruit-esp32-feather-v2/factory-reset) # No-Code DS18B20 Temperature Sensor with WipperSnapper ## WipperSnapper ## Usage Assuming you have already gone through the WipperSnapper Setup page and connected your board to WipperSnapper, **[navigate to the WipperSnapper board list](https://io.adafruit.com/wippersnapper).** On this page,  **select the WipperSnapper board you just connected**. - If you do not see your board listed - go back to the WipperSnapper Setup Page and make sure it registers with Adafrut.io ![](https://cdn-learn.adafruit.com/assets/assets/000/117/079/medium800/adafruit_io_ksnip_20221214-141506.png?1671045356) On the device page, quickly  **check that your device is online and is running the latest version of the WipperSnapper firmware**. The device tile on the left indicates the version number of the firmware running on the connected board. - **If the firmware version is green with a checkmark -**  continue with this guide. - **If the firmware version is red with an "X" -**  [update to the latest WipperSnapper firmware](https://learn.adafruit.com/quickstart-adafruit-io-wippersnapper) on your board before continuing. ![adafruit_io_ksnip_20221214-141639.png](https://cdn-learn.adafruit.com/assets/assets/000/117/082/medium640/adafruit_io_ksnip_20221214-141639.png?1671045456) ![temperature___humidity_04_UpdateRequired.png](https://cdn-learn.adafruit.com/assets/assets/000/127/953/medium640/temperature___humidity_04_UpdateRequired.png?1708714082) **Click the New Component button or the + button ** to bring up the component picker. ![](https://cdn-learn.adafruit.com/assets/assets/000/117/083/medium800/adafruit_io_ksnip_20221214-142536.png?1671045962) Adafruit IO supports a large amount of components. To quickly find your sensor, type `DS18B20` into the search bar, then select the image matching your **DS18B20**  sensor. ![](https://cdn-learn.adafruit.com/assets/assets/000/127/954/medium800/temperature___humidity_DS18B20.png?1708714705) On the component configuration page, the **DS18B20**'s pin and resolution can be changes, along with selecting some or all of the available metrics to be published. First, select pin D14 as the DS18B20 Pin. Next, select how you'd like the temperature to be displayed on Adafruit IO. - Adafruit is located in New York. We've selected the degrees Fahrenheit option to match our locale.  Then, set the Send Every measurement option to **Every 30 seconds** - The  **Send Every**  option tells the sensor how often to report new measurements to Adafruit IO. The measurement interval can range from every 30 seconds to every 24 hours. Finally, click **Create Component** ![](https://cdn-learn.adafruit.com/assets/assets/000/117/086/medium800/adafruit_io_ksnip_20221214-144702.png?1671047296) Your device interface should now show a new block displaying the value of the DS18B20 component. After the sensor measurement interval elapses, WipperSnapper will automatically read the temperature value from the DS18B20 and send it to Adafruit IO. ![](https://cdn-learn.adafruit.com/assets/assets/000/117/089/medium800thumb/adafruit_io_ezgif.com-gif-maker_%281%29.jpg?1671053335) Sensor data is also logged to Adafruit IO and retained for up to 60 days (on IO Plus, Paid, plans)! To view the data that has been logged from the sensor, click on the graph icon. ![](https://cdn-learn.adafruit.com/assets/assets/000/117/087/medium800/adafruit_io_ksnip_20221214-154505.png?1671050723) Here you can see the sensor's history and edit things about the feed such as the privacy, webhooks associated with the data feed, and more. If you want to learn more about how feeds work, [check out this page](https://learn.adafruit.com/all-the-internet-of-things-episode-four-adafruit-io/advanced-feeds). ![](https://cdn-learn.adafruit.com/assets/assets/000/117/088/medium800/adafruit_io_ksnip_20221214-161043.png?1671052258) For IO Free accounts, feed data is stored for a maximum of 30 days and there's a maximum of 10 feeds. You also get 2 WipperSnapper devices in the free plan (IO+ has unlimited), but normal Adafruit IO Web/MQTT clients _do not count_ against this limit. In this guide you created one WipperSnapper device, and one WipperSnapper component (DS18B20), which automatically created one feed for each of the enabled component metrics, e.g. one for Temperature in degrees Fahrenheit and an additional one if you enable the reporting of Temperature in degrees Celsius. If you’d like to store data for more than 30 days, increase the number of feeds (components), add additional devices you can use with WipperSnapper, or increase your data rate to send more sensor measurements to Adafruit IO - [upgrade your account to Adafruit IO Plus](https://io.adafruit.com/plus). ## Guide Products ### Adafruit ESP32 Feather V2 - 8MB Flash + 2 MB PSRAM [Adafruit ESP32 Feather V2 - 8MB Flash + 2 MB PSRAM](https://www.adafruit.com/product/5400) One of our star Feathers is the [Adafruit HUZZAH32 ESP32 Feather](https://www.adafruit.com/product/3405) - with the fabulous ESP32 WROOM module on there, it makes quick work of WiFi and Bluetooth® projects that take advantage of Espressifs most popular chipset.
