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