Siemens Building Technology QPA2062 Co2Roomsensor0-10Vdc Temp/Rh

The Siemens Building Technology QPA2062 is a room sensor that detects CO2, temperature, and relative humidity. These measured values are sent to a Building Management System (BMS) or controller via a 0–10V DC voltage signal. Typically, this sensor is used to monitor and regulate the comfort and quality of indoor air in HVAC (Heating, Ventilation, and Air Conditioning) equipment. Increased energy efficiency, improved indoor air quality, and increased occupant comfort can all result from using this sensor. A nondispersive infrared sensor is used by the QPA2062 to measure CO2 levels. This kind of sensor measures the amount of infrared light absorbed by CO2 molecules using a light source and a detector. The proportion of CO2 in the air to the amount of light absorbed.
