M5Stack: Temperature, Pressure, Humidity (QMP9688+SHT30), I2C, Grove

Pressure/Temperature/Humidity Environmental Sensor (SHT30+QMP6988)

This is a environmental sensor used to sense temperature, humidity and atmospheric pressure all enclosed inside a small case and using a Grove connector.

It integrates the SHT30 for temperature and humidity sensing as well as the QMP6988 sensor for the pressure measurement (similar to the famous BMP280).

SHT30 is a well known digital temperature and humidity sensor with high precision and low power consumption.
The QMP6988 is an absolute air pressure sensor designed for mobile application. It offer stability abd accuracy measurements.

The sensors can be queried over the I2C bus so only 2 wires are required to transmit the data (SHT30 @ 0x44, QMP6988 @ 0x70).

This unit features:

• High-precision
• Support I2C
• GROVE interface
• Two Lego installation holes
