M5Stack ENV III Unit is an environmental sensor that can detect temperature, humidity, and atmospheric pressure. This unit integrates the SHT30 and QMP6988 sensors and supports the I²C interface. The SHT30 is a digital temperature and humidity sensor with high precision and low power consumption. The QMP6988 is an absolute air pressure sensor that is designed for mobile applications with high accuracy and stability. This sensor unit features a -40°C to 120°C temperature measuring range and 300hPa to 1100hPa air pressure measuring range. The ENV III environmental sensor is ideally suitable for environmental data collection and detection types of projects.
