Air quality sensor module MMJ1013 is developed using MEMS micro gas sensors. It can be used to detect the TVOC gas in the environment and then determine the air quality. This module has extremely high sensitivity to organic volatile gases such as formaldehyde, benzene, carbon monoxide, ammonia, hydrogen, alcohol, cigarette smoke, and spices.
The module can be used for air purifier, indoor air monitoring, air conditioner or ventilate system to fresh air, portable detector.
