This unit consist of Optics, Temperature Sensor Signal amplifier, Processing circuit and LCD Display.

The Optics collected the infrared energy emitted by object and focus onto the Sensor.

Then the sensor translates the energy into an electricity signal.  This signal will be

turned out to be digital shown on the LCD after the signal amplifier and

processing circuit.
