ens160 0.0.2

ENS160 Air Quality Sensor driver

ENS160

ENS160 Python library.

Datasheet

This code was tested on a Raspberry Pi 5 at 100kHz I2C clock.

The I2C code is abstracted from the sensor handling and other communication methods could be added.

Tested with Python 3.12

Documentation

The detailed API documentation can be found here.

Install

pip install ens160
