M5Stack M5StickC ENV III HAT

The ENV III HAT is a multifunctional environmental sensor compatible with the M5Stack M5StickC series. It integrates an SHT30 and QMP6988 sensor internally to detect temperature, humidity and atmospheric pressure data.

The SHT30 (0x44) is a high-precision, low-power digital temperature sensor. The QMP6988 (0x56) is an absolute air pressure sensor specially designed for mobile applications with high accuracy.

For projects that require rapid collection and detection of environmental data, ENV-III HAT is a balanced performance A good choice for cost performance.
