M5Stack Module - Environmental

M5Stack is a robust, Arduino compatible, open source development kit with stackable modules, enabling rapid and high-quality IoT prototyping.

This M5Stack Environmental Module is designed for sensing temperature, humidity and barometric pressure. It features two sensors - BMP280 for barometric pressure sensing and DHT11 to measure temperature and humidity. Because pressure changes with altitude, and the pressure measurements by BMP280 are so good, you can also use it as an altimeter with ±1 meter accuracy.

The module uses I2C interface.
