Unit ENV-Pro
SKU:U169
Description
The Unit ENV-Pro sensor is a highly integrated environmental detection unit, equipped with the BME688 sensor solution. It supports the measurement of various environmental parameters such as VOCs (volatile organic compounds), CO₂ equivalent, indoor air quality (IAQ), temperature, humidity, and atmospheric pressure. The sensor uses an I2C communication interface (0x77), making it suitable for applications like weather stations, indoor environment monitoring, and air quality detection.
