Find Out All About How an HVAC Sensor Works for Your Home

An HVAC sensor is technology that links to your central thermostat to make heating and cooling your home more effective and more efficient. Most often, these HVAC sensors are utilized in zoning systems that individualize the flow of conditioned air into predetermined zones. In today’s most advanced systems, the “zone” may actually be a single room rather than a larger, multiroom area.

 Sensors Make Your System Smarter

The purpose of an HVAC sensor is to communicate information to the thermostat—which also functions as the central brain of the system—about the status of a zone or room. Primarily, this information includes room-temperature data. With more advanced systems, the sensor may also detect whether occupants are present in a given room or the space is empty at a specific time.

Customized Airflow and Temperature Control

To individualize temperatures for a particular room or zone, the flow of heated or cooled air into that space must be controlled. Electronically operated modulating dampers installed inside the home’s ductwork can be opened and closed by signals from the central thermostat. If a thermostat setting in an individual room or zone requires more heat, for example, the central unit opens the damper to admit warm airflow to that space. Once the sensor reports that the temperature has reached the desired setting, the central unit closes the damper and conditioned airflow stops.

If a sensor includes an occupancy-detection function, the system may also return the temperature to a predetermined “vacant” setting to preserve maximum energy efficiency once the sensor determines that all occupants have left a single room or zone.

Additional Uses

Sensors incorporated in more advanced HVAC systems may also track humidity levels in a certain space or room. The system can then activate a humidifier or dehumidifier installed inside ductwork to adjust the humidity to preset levels for optimum comfort.
