Description
Supply voltage:DC5V
Board size:53*32mm
Function Description:
This circuit design can achieve high sensitivity when the buzzer sounds and the LED light turns on when approaching the infrared emission tube and infrared receiver tube with your hand. Once the hand is moved away, the sound immediately stops and the LED light turns off. The design concept of this circuit comes from the life scene of a bank automatically opening and closing doors. When a person enters the bank, the door automatically opens and when they leave, the back door automatically closes. The production of infrared sensing circuits is mainly aimed at learning the working principles and usage methods of infrared emission tubes and infrared receiver tubes, and mastering the practical application of the universal operational amplifier LM358 as an operational comparator
Introduction to Key Components: The infrared sensing circuit consists of an infrared sensing circuit with an infrared emitter tube, D1, and infrared receiver tube D2 as the core, a sampling and comparison circuit with an adjustable resistor R3 and a universal operational amplifier LM358 as the core, and a sound output and display circuit with a triode 9012 V1, V2 buzzer Y1, and LED D3 as the core components
