It's easy to use the ADT7410 sensor with Python or CircuitPython, and the Adafruit CircuitPython ADT7410 module. This module allows you to easily write Python code that reads temperature from the 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.

CircuitPython Microcontroller Wiring

First wire up a ADT7410 to your board exactly as shown on the previous page for Arduino. 

Make the following connections between the CircuitPython board and the ADT7410:

  • Board 3V to ADT7410 VIN
  • Board GND to ADT7410 GND
  • Board SCL to ADT7410 SCL
  • Board SDA to ADT7410 SDA

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

Make the following connections between the Pi and the ADT7410:

  • Pi 3V to ADT7410 VIN
  • Pi GND to ADT7410 GND
  • Pi SCL to ADT7410 SCL
  • Pi SDA to ADT7410 SDA

Python Installation of ADT7410 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!

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

  • sudo pip3 install adafruit-circuitpython-adt7410

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 Installation of ADT7410 Library

To use with CircuitPython, you need to first install the Adafruit CircuitPython ADT7410 library, and its dependencies, into the lib folder on your CIRCUITPY drive. Then you need to update 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 file in a zip file. Extract the contents of the zip file, and copy the entire lib folder and the file to your CIRCUITPY drive.

Your CIRCUITPY/lib folder should contain the following folders and file:

  • adafruit_adt7410.mpy
  • /adafruit_bus_device
  • /adafruit_register

import time
import board
import adafruit_adt7410

i2c = board.I2C()  # uses board.SCL and board.SDA
# i2c = board.STEMMA_I2C()  # For using the built-in STEMMA QT connector on a microcontroller
adt = adafruit_adt7410.ADT7410(i2c, address=0x48)
adt.high_resolution = True

while True:

Python Usage

To demonstrate the usage of the ADT7410, we'll use the Python REPL.

First, we'll import the following modules:

import time
import board
import busio
import adafruit_adt7410

Next, we'll initialize the I2C bus and create the ADT object. We'll set it's high_resolution property to True, to use 16-bit resolution (instead of the default 13-bit).

i2c_bus = busio.I2C(board.SCL, board.SDA)
adt = adafruit_adt7410.ADT7410(i2c_bus, address=0x48)
adt.high_resolution = True

You can read the temperature using the .temperature property (the output will be in degrees Celsius). Try putting your finger on the sensor or holding it against something cold to see the values change.


You can convert to Fahrenheit by multiplying by 1.8 and adding 32:

tempC = adt.temperature
tempF = tempC * 1.8 + 32.0

That's all there is to reading the temperature with the ADT7410. Now you can use the ADT7410 temperature sensor to read the temperature in your project!
