Abstract
A system and method is presented for a multi-sensor component for an HVAC system. The multi-sensor component comprises a sensor assembly, having a temperature detector for measuring a temperature of an object or medium, a presence detector to detect the presence of the object or medium against the sensor, and a pressure detector for measuring a pressure of the medium. The temperature, presence and pressure detectors may also be affixed within a single sensor housing. In a heating mode the multi-sensor component is heated by a heater, and in a cooling mode the multi-sensor component cools toward a temperature of the object or medium, and the temperature detector provides temperature data indicative of a temperature response comprising one of a temperature change, a rate of change and a time constant of a thermal decay rate of the multi-sensor component and the presence of the object or medium.
