Abstract
A multifunction sensor device (10) provides various transducer functions for performing temperature sensing, humidity sensing, ambient light sensing, motion detection, thermostat functions, switching functions, load switching and dimming functions, displaying actual and set temperature values, displaying time of day values apparatus for putting the device in an on/off or auto mode. Key elements include mounting the diverse sensors or transducers within the same housing (14) that can be mounted to a wall in a flush manner, eliminating the requirement of an air flow channel in the device (10), thus minimizing any adverse effects on the motion detecting element or sensor. The device can transmit and receive real time data, relative data and actual discrete data in addition to switching and controlling loads locally or remotely.
