HVAC Sensors
An HVAC sensor is any device used to measure the conditions of an enclosed space, room, or building. HVAC sensors include thermostats, humidistats, carbon dioxide sensors, pressure sensors, and more.
HVAC sensors are connected to equipment and regulate air quality. Thermostats measure temperature, switching on and off heaters and air conditioners so that the measured temperature matches a predetermined setpoint. Humidistats measure humidity and work with thermostats and heaters to protect equipment from condensation and corrosion. Carbon dioxide sensors monitor the quality of the air and regulate fresh air with ventilation adjustments. Pressure sensors monitor and adjust airflow.
HVAC sensors are ultimately responsible for the efficiency of the entire HVAC system and the overall air quality of the environment.
