## Overview

![](https://cdn-learn.adafruit.com/assets/assets/000/094/206/medium800/adafruit_products_guide_4716_iso_ORIG_2020_08.png?1597791242)

Because of their many applications, Pressure, Temperature, and Humidity sensors (PHT sensors) are a common offering from semiconductor companies. The MS8607 PHT sensor from TE Connectivity  does an admirable job of measuring a wide range of all three environmental conditions. Each and every MS8607 sensor is calibrated at the factory and the calibration constants stored in the sensor itself. This sensor is a one stop shop for all your common weather and environmental related metrics. Just add a MS8607 and you’ll be ready to finish your enclosure and retire as a [Dubia Cockroach Farmer](https://dubiaroachdepot.com/guidance/breeding-dubia-roaches#thermometer)

![](https://cdn-learn.adafruit.com/assets/assets/000/094/207/medium800/adafruit_products_guide4716_kit_ORIG_2020_08.png?1597791401)

The MS8607 provides the previously mentioned factory-calibrated pressure, temperature, and humidity data are recorded as **16-bit** values and made available over an I2C bus for simple, two wire (plus power and ground!) connection to your microcontroller. Pressure measurements accuracy comes in at **+/- 2 hPa** , relative humidity at **+/- 3% rH** , and temperature is good to within **1 degree** Celsius. One standout feature of the MS8607 is it’s very respectable low power consumption at **as low as 0.78 µA !** That’s hardly anything! Along with carefully managed microcontroller power usage, getting good battery life out of your sensing project will be that much easier.

While the MS8607 sensor itself is rotund by comparison to some of the other sensors we stock, it’s still a surface mount part so we’ve placed it on a breakout board, nestled amongst a handful components that take care of level shifting and power regulation. This lets you use it with either 5V or 3.3V devices, so no matter if you have an Arduino, Metro, Feather, or Raspberry Pi, you’ll be able to interface with the MS8607 easily. The breakout has the expected header for power and I2C connections, however if you prefer to or can’t solder, you can use the [SparkFun Qwiic](https://www.sparkfun.com/qwiic) compatible [STEMMA QT](https://learn.adafruit.com/introducing-adafruit-stemma-qt) connectors to wire up to your favorite micro with a  [plug-and-play cable](https://www.adafruit.com/?q=stemma%20qt%20cable). Even if like me you don’t mind soldering, STEMMA QT connectors are super convenient for wiring up projects quickly.

## Pinouts

![](https://cdn-learn.adafruit.com/assets/assets/000/094/210/medium800/adafruit_products_guide_4716_top_ORIG_2020_08-2.png?1597791613)

 **Power Pins**

- **VIN** - this is the power pin. Since the sensor chip uses 3 VDC, we have included a voltage regulator on board that will take 3-5VDC and safely convert it down. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V microcontroller like Arduino, use 5V
- **3Vo**  - this is the 3.3V output from the voltage regulator, you can grab up to 100mA from this if you like
- **GND** - common ground for power and logic

## **I2C Logic Pins**

- **SCL** - I2C clock pin, connect to your microcontroller I2C clock line. This pin is level shifted so you can use 3-5V logic, and there's a **10K pullup** on this pin.
- **SDA** - I2C data pin, connect to your microcontroller I2C data line. This pin is level shifted so you can use 3-5V logic, and there's a **10K pullup** on this pin.
- [**STEMMA QT**](https://learn.adafruit.com/introducing-adafruit-stemma-qt) ** -** These connectors allow you to connectors to dev boards with  **STEMMA QT** connectors or to other things with [various associated accessories](https://www.adafruit.com/?q=JST%20SH%204)

# Adafruit TE MS8607 PHT Sensor

## Arduino

Using the MS8607 with Arduino is a simple matter of wiring up the sensor to your Arduino-compatible microcontroller, installing the [Adafruit MS8607](https://github.com/adafruit/Adafruit_MS8607) library we've written, and running the provided example code.

## **I2C Wiring**

Use this wiring if you want to connect via I2C interface. The MS8607 is actually two devices in the same package so the I2C address for the pressure sensor is **0x76** and the address for the humidity sensor is **0x40.**

Here is how to wire up the sensor using one of the [**STEMMA QT**](https://learn.adafruit.com/introducing-adafruit-stemma-qt) connectors. The examples show a Metro but wiring will work the same for an Arduino or other compatible board.

- Connect **board VIN (red wire)** to  **Arduino 5V**  if you are running a **5V** board Arduino (Uno, etc.). If your board is **3V,** connect to that instead.
- Connect **board GND (black wire) **to  **Arduino**  **GND**
- Connect **board SCL (yellow wire) **to  **Arduino**  **SCL**
- Connect **board SDA (blue wire) **to  **Arduino**  **SDA**

![adafruit_products_image.png](https://cdn-learn.adafruit.com/assets/assets/000/094/211/medium640/adafruit_products_image.png?1597792147)

Here is how to wire the sensor to a board using a solderless breadboard:

- Connect **board VIN (red wire)** to  **Arduino 5V**  if you are running a **5V** board Arduino (Uno, etc.). If your board is **3V,** connect to that instead.
- Connect **board GND (black wire) **to  **Arduino**  **GND**
- Connect **board SCL (yellow wire) **to  **Arduino**  **SCL**
- Connect **board SDA (blue wire) **to  **Arduino**  **SDA**

## Python & CircuitPython

It's easy to use the **MS8607** with Python or CircuitPython, and the [Adafruit CircuitPython MS8607](https://github.com/adafruit/Adafruit_CircuitPython_MS8607) module. This module allows you to easily write Python code that reads pressure, humidity and temperature from the **MS8607** sensor.

You can use this sensor with any CircuitPython microcontroller board or with a computer that has GPIO and Python [thanks to Adafruit\_Blinka, our CircuitPython-for-Python compatibility library](https://learn.adafruit.com/circuitpython-on-raspberrypi-linux).

## **CircuitPython Microcontroller Wiring**

First wire up a MS8607 to your board exactly as shown below. Here's an example of wiring a Feather M4 to the sensor with I2C using one of the handy [**STEMMA QT**](https://learn.adafruit.com/introducing-adafruit-stemma-qt) connectors:

- **Board 3V**  to **sensor VIN (red wire)**
- **Board GND**  to **sensor GND (black wire)**
- **Board SCL**  to **sensor SCL (yellow wire)**
- **Board SDA**  to **sensor SDA (blue wire)**

![adafruit_products_image.png](https://cdn-learn.adafruit.com/assets/assets/000/094/075/medium640/adafruit_products_image.png?1597424744)

You can also use the standard **0.100" pitch** headers to wire it up on a breadboard:

- **Board 3V**  to **sensor VIN (red wire)**
- **Board GND**  to **sensor GND (black wire)**
- **Board SCL**  to **sensor SCL (yellow wire)**
- **Board SDA**  to **sensor SDA (blue wire)**

![adafruit_products_image.png](https://cdn-learn.adafruit.com/assets/assets/000/094/076/medium640/adafruit_products_image.png?1597425005)

## **Python Computer Wiring**

Since there's _dozens_ of Linux computers/boards you can use, we will show wiring for Raspberry Pi. For other platforms, [please visit the guide for CircuitPython on Linux to see whether your platform is supported](https://learn.adafruit.com/circuitpython-on-raspberrypi-linux). 

Here's the Raspberry Pi wired to the sensor using I2C and a [**STEMMA QT**](https://learn.adafruit.com/introducing-adafruit-stemma-qt) connector:

- **Pi 3V**  to **sensor VCC (red wire)**
- **Pi GND**  to **sensor GND (black wire)**
- **Pi SCL**  to **sensor SCL (yellow wire)**
- **Pi SDA**  to **sensor SDA (blue wire)**

![adafruit_products_image.png](https://cdn-learn.adafruit.com/assets/assets/000/094/079/medium640/adafruit_products_image.png?1597425204)

Finally here is an example of how to wire up a Raspberry Pi to the sensor using a solderless breadboard

- **Pi 3V**  to **sensor VCC (red wire)**
- **Pi GND**  to **sensor GND (black wire)**
- **Pi SCL**  to **sensor SCL (yellow wire)**
- **Pi SDA**  to **sensor SDA (blue wire)**

![adafruit_products_image.png](https://cdn-learn.adafruit.com/assets/assets/000/094/081/medium640/adafruit_products_image.png?1597425586)

## **CircuitPython Installation of MS8607 Library**

You'll need to install the [Adafruit CircuitPython MS8607](https://github.com/adafruit/Adafruit_CircuitPython_MS8607) library on your CircuitPython board.

First make sure you are running the [latest version of Adafruit CircuitPython](https://learn.adafruit.com/welcome-to-circuitpython/installing-circuitpython) 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://circuitpython.org/libraries).  Our CircuitPython starter guide has [a great page on how to install the library bundle](https://learn.adafruit.com/welcome-to-circuitpython/circuitpython-libraries).

Before continuing make sure your board's **lib** folder or root filesystem has the **adafruit\_ms8607.mpy** file **and adafruit\_bus\_device** folder ** ** copied over.

Next [connect to the board's serial REPL ](https://learn.adafruit.com/welcome-to-circuitpython/the-repl)so you are at the CircuitPython  **\>\>\>**  prompt.

## **Python Installation of MS8607 Library**

You'll need to install the **Adafruit\_Blinka** library that provides the CircuitPython support in Python. This may also require enabling I2C on your platform and verifying you are running Python 3. [Since each platform is a little different, and Linux changes often, please visit the CircuitPython on Linux guide to get your computer ready](https://learn.adafruit.com/circuitpython-on-raspberrypi-linux)!

Once that's done, from your command line run the following command:

- `sudo pip3 install adafruit-circuitpython-ms8607`

If your default Python is version 3 you may need to run 'pip' instead. Just make sure you aren't trying to use CircuitPython on Python 2.x, it isn't supported!

## **CircuitPython & Python Usage**

To demonstrate the usage of the sensor we'll initialize it and read the pressure, temperature, and humidity measurements from the board's Python REPL.

Run the following code to import the necessary modules and initialize the I2C connection with the sensor:

```python
import board
import busio
from adafruit_ms8607 import MS8607

i2c = busio.I2C(board.SCL, board.SDA)
sensor = MS8607(i2c)
```

![](https://cdn-learn.adafruit.com/assets/assets/000/093/900/medium800/adafruit_products_image.png?1596767866)

Now you're ready to read values from the sensor using these properties:

- **relative\_humidity** - The relative humidity measured by the sensor, this is a value from 0-100%.
- **temperature ** - The temperature measured by the sensor, a value in degrees Celsius.
- **pressure** - The pressure measured by the sensor, a value in hectopascals (hPa)

```python
print("Pressure: %.2f hPa" % sensor.pressure)
print("Temperature: %.2f C" % sensor.temperature)
print("Humidity: %.2f %% rH" % sensor.relative_humidity)
```

## 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.

If you've never used WipperSnapper, click below to read through the quick start guide before continuing.

[Quickstart: Adafruit IO WipperSnapper](https://learn.adafruit.com/quickstart-adafruit-io-wippersnapper)
## Wiring
First, wire up an MS8607 to your board exactly as follows. Here is an example of the MS8607 wired to an [Adafruit ESP32 Feather V2](https://www.adafruit.com/product/5400) using I2C [with a STEMMA QT cable (no soldering required)](https://www.adafruit.com/product/4210)

- **Board 3V**  to **sensor VIN (red wire on STEMMA QT)**  
- **Board GND**  to **sensor GND (black wire on STEMMA QT)**  
- **Board SCL**  to **sensor SCL (yellow wire on STEMMA QT)**  
- **Board SDA**  to **sensor SDA (blue wire on STEMMA QT)**

![adafruit_products_featherV2_MS8607_bb.png](https://cdn-learn.adafruit.com/assets/assets/000/124/133/medium640/adafruit_products_featherV2_MS8607_bb.png?1693408003)

![adafruit_products_featherV2_MS8607_Breadboard_bb.png](https://cdn-learn.adafruit.com/assets/assets/000/124/134/medium640/adafruit_products_featherV2_MS8607_Breadboard_bb.png?1693408025)

## Usage

Connect your board to Adafruit IO Wippersnapper and **[navigate to the WipperSnapper board list](https://io.adafruit.com/wippersnapper).**

On this page, **select the WipperSnapper board you're using** to be brought to the board's interface page.

![](https://cdn-learn.adafruit.com/assets/assets/000/124/135/medium800/adafruit_products_8d2qSSHZ2S_arrow.png?1693408063)

If you do not see your board listed here - you need [to connect your board to Adafruit IO](https://learn.adafruit.com/quickstart-adafruit-io-wippersnapper) first.

On the device page, quickly  **check that you're 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 exclamation mark "!" -**  [update to the latest WipperSnapper firmware](https://learn.adafruit.com/quickstart-adafruit-io-wippersnapper) on your board before continuing.

![adafruit_products_CroppedVersion.png](https://cdn-learn.adafruit.com/assets/assets/000/124/136/medium640/adafruit_products_CroppedVersion.png?1693408101)

![adafruit_products_DeviceListPage_UpdateRequired.png](https://cdn-learn.adafruit.com/assets/assets/000/124/137/medium640/adafruit_products_DeviceListPage_UpdateRequired.png?1693408119)

Next, make sure the sensor is plugged into your board and click the ** I2C Scan ** button.

![](https://cdn-learn.adafruit.com/assets/assets/000/113/177/medium800/sensor_page_crop_scan.png?1657724520)

The MS8607 is actually two devices in the same package so the I2C address for the pressure sensor is  **0x76 ** and the address for the humidity sensor is  **0x40.**

You should see the MS8607's I2C addresses of `0x40` and `0x76` pop-up in the I2C scan list.

![](https://cdn-learn.adafruit.com/assets/assets/000/124/138/medium800/adafruit_products_Screenshot_2023-08-30_155333.png?1693408263)

###  I don't see the sensor's I2C address listed! 


First, double-check the connection and/or wiring between the sensor and the board.

Then, reset the board and let it re-connect to Adafruit IO WipperSnapper.

With the sensor detected in an I2C scan, you're ready to add the sensor to your board.

**Click the New Component button or the + button** to bring up the component picker.

![](https://cdn-learn.adafruit.com/assets/assets/000/127/931/medium800/sensor_page_temperature___humidity_06_AddComponent.png?1708631009)

Adafruit IO supports a large amount of components. To quickly find your sensor, type `MS8607` into the search bar, then select the **MS8607****  **component.

![](https://cdn-learn.adafruit.com/assets/assets/000/127/946/medium800/adafruit_products_kqkCqYcRdh.png?1708698361)

On the component configuration page, as the MS8607 is actually two devices in the same package, the address for the humidity sensor ** ** should be listed along with the sensor's settings.

Warning: 

The  **Send Every**  option is specific to each sensor's measurements. This option will tell the Feather how often it should read from the MS8607 sensor and send the data to Adafruit IO. Measurements can range from every 30 seconds to every 24 hours.

For this example, set the  **Send Every ** interval to every 30 seconds.

![](https://cdn-learn.adafruit.com/assets/assets/000/124/141/medium800/adafruit_products_Screenshot_2023-08-30_161759.png?1693408695)

Your device interface should now show the sensor components you created. After the interval you configured elapses, WipperSnapper will automatically read values from the sensor(s) and send them to Adafruit IO.

![](https://cdn-learn.adafruit.com/assets/assets/000/124/142/medium800/adafruit_products_zrDEJOgV03.png?1693408795)
