WL-AQD-A01 is especially used to detect indoor air quality. It can detect the level of CO2, temperature, humidity and VOC, which is helpful to control related devices and ensure excellent living condition
Main Features
Detect indoor air parameters including CO2, temperature & humidity and VOC
Compact appearance and reasonable price
Automatically control devices such as AC.
Production Description
It can be also mounted in the existed or being installed ventilation system to reduce the installation cost.
WL-AQD-01 integrates 4 sensors which can measure the level of CO2, temperature, humidity and VOC indoor at the same time. The air quality changes at any point indoor will be detected and the data collected will be transferred through RS485 and RS232 interface to realize the function of intelligent control of AC, humidifier and other ventilations etc.
