Unit ENV
Description
Unit ENV is an environmental sensor that integrates DHT12 and BMP280 internally for detecting temperature, humidity, and atmospheric pressure data. The DHT12 is an upgraded version of the DHT11 humidity and temperature sensor, fully backward compatible, offering more accurate measurements and an added I2C interface. The BMP280 is an absolute barometric pressure sensor designed for mobile applications, featuring high accuracy. It is suitable for small, low-power terminals. For projects that require rapid environmental data collection and detection, Unit ENV is an excellent choice that balances performance and cost-effectiveness.
