Abstract
A sensor system includes a housing that houses a thermally sensitive sensor, a transmitter portion and a power source. Preferably, the sensor device is encapsulated to protect the components from the environment. When the temperature in a component mounting the sensor system exceeds a preselected threshold, the thermostat sensor closes and the transmitter portion is energized by the power source to transmit a signal to a receiver unit.
