sensor for air quality control

Use of VOC sensors for air quality control of building ...

Air quality control with VOC (volatile organic compound) sensors in residential buildings could increase user comfort by adapting to the actual contaminant level. Preliminary tests assessed the dynamics of VOC levels in single-family passive houses with a ventilation system. At normal and exceptional usages, sufficient signal variations were measured for air quality control.

Air pollution sensor, control and monitor air quality | Airly

Sensors measure the particulates using the laser method. In the case of gas pollutants, our single device is able to measure two chemical compounds by electro-chemical method. Readings are taken from two cells installed in the gas module of the sensor. Each sensor has a special light diode that changes to clearly show the current air quality using a colour consistent with the CAQI scale.
