Integrated circuit LM3911 is a silicon sensor composed of operational amplifier and voltage regulator circuit.It can be a simple electrical thermometer only by using a few external components.Transistor is used as a temperature-sensing element on the silicon chip.The voltage of base and emitter of the transistor varies with temperature changes.When the temperature rises,the voltage will increase.Outside temperature intussuscepted from a copper billet will be passed on to the temperature sensor.The copper billet will be connected to pins 5~8 of the integrated circuit and the inside parts of these pins are connected to temperature sensor.
