Description
The Siemens QPM2100 duct air quality sensor is part of the Siemens Symaro range of building automation sensors. It measures CO₂ concentration in air flowing through ventilation ducts, providing a signal that a compatible building management or HVAC control system can use to monitor indoor air quality.
The sensor is intended for ventilation systems in offices, commercial buildings, schools, meeting spaces, and other occupied indoor environments where CO₂ monitoring supports ventilation control. Siemens specifies that this sensor family is not suitable for safety-related applications, such as gas or smoke alarm systems.
