Unit ENV

SKU:U001

Description

ENV is a environmental sensor, can be used for temperature, humidity, and atmospheric pressure measurement.

The ENV sensor integrates DHT12 and BMP280 sensors.

DHT12 is an upgraded version of DHT11 humidity temperature sensor: complete downward compatibility, higher precision and added I2C interface.

BMP280 is an absolute barometric pressure sensor especially designed for mobile applications, offers highest flexibility to optimize the device regarding power consumption, resolution and filter performance.
