Indoor T, H, CO2, VOC and PM sensors

The CAREL DPWQ* sensors measure the most important parameters that determine indoor air quality: temperature, relative humidity, CO₂ (carbon dioxide), VOC (volatile organic compounds), PM2.5 and PM10 (particulate matter). 
The measured parameters can be viewed directly on the display and/or used to control various mechanical ventilation and air purification systems, either via RS485 serial communication or a proportional signal. 
Integration of indoor air quality probes into the control of building ventilation systems helps combine the need to control energy consumption with the guarantee of a healthy and comfortable indoor environment. Maintaining an adequate indoor air quality level protects human health and productivity in shopping centres, offices, theatres, museums and other environments.
