ABSTRACT:
A sensor circuit provides a signal to a microcontroller to indicate parameters of an environmental condition to which the sensor circuit is exposed, such as temperature. The sensor circuit and microcontroller are mounted in a common housing, with an output lead indicating an on/off output based on predetermined parameters of the environmental condition. By access through the output lead, the microcontroller can be reprogrammed to change the predetermined parameters controlling the output state of the switch.
