M5Stack Environment Sensor Unit III

ENV III is an environmental sensor that integrates SHT30 and QMP6988 internally to detect temperature, humidity, and atmospheric pressure data. SHT30 is a high-precision and low-power digital temperature and humidity sensor, and supports I2C interface (SHT30:0x44 , QMP6988:0x70).QMP6988 is an absolute air pressure sensor specially designed for mobile applications, with high accuracy and stability, suitable for environmental data collection and detection types of projects.

This Unit communicates with the M5Core via GROVE B.

Note:

1. This unit is actually an add-on unit for M5Stack controllers. The controllers are NOT INCLUDED in the package. However, it is compatible with the following controllers:
   • M5Stack Basic ESP32
   • M5Stack Fire ESP32
   • M5Stack ATOM Matrix ESP32
2. If you're interested to get other M5Stack modules and units in your hands for a lot more fun projects, you may get them here.
