Introduction In the world of embedded systems and robotics, few components are as ubiquitous or as essential as the infrared proximity sensor. Among the myriad of options available, the FC-51 IR Sensor stands out as a favorite for hobbyists and professionals alike. It is cheap, reliable, easy to interface with microcontrollers like Arduino, Raspberry Pi, and ESP32, and incredibly effective for non-contact object detection. Fc 51 Ir Sensor Datasheet

void loop() sensorState = digitalRead(sensorPin); GPIO.IN) void loop() sensorState = digitalRead(sensorPin)
The FC-51 can run on 3.3V, making it safe for Pi GPIO. Use the same pinout but connect VCC to 3.3V.
