Abstract
A multifunction sensor device acts as a heat detector and performs various transducer functions for temperature sensing, ambient light sensing, motion detection, switching functions, and a mechanism to put the device in an on, off or auto mode. The device operates in diverse environments in which sensors are utilized for energy monitoring and control, end user convenience or HVAC control. Key elements include overcoming the difficulty of mounting diverse sensors or transducers within the same device or housing; permitting these various sensors to exist in a single package mounted to a wall; and eliminating the requirement of an air flow channel, thus minimizing any adverse effects on the motion detecting element or sensor as well as providing built in partial hysteresis. A temperature sensor is exposed neither to the flow of air in a room or area nor in an airflow channel where a chimney effect may occur.
