Unit ENV-III
Description
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.
