Detector capable of signaling the change of temperature, and then a heat source, through an active signal to the low level outgoing from pin OUT. The detection takes place through an LM393 amplifier (in the configuration of the voltage comparator), and the adjustment is made by means of a precision trimmer on board of the small circuit.
It can be used to detect open flames, temperature changes, in smart car and for many other applications.
