Temperature sensitive circuit, controlling a relay. The 1k resistor on the bottom left is your thermistor of sorts. Increase or decrease the value ever so slightly and watch the opamp output change the state of the relay. Changing the value simulates temp change on a monitored device. Vcc of the opamp and reley drive power can be altered to suit individual needs.
