TCRT5000 Sensor Features
The TCRT5000 Sensor is used to detect color and distance. The sensor emits an infrared wave and then receives it. TCRT5000 Infrared Reflective Sensor Module is often used in line following robots and object sorting Robots since this module can sense if a surface is white or black.
The measuring distances range from 1mm to 8mm and the central point is about 2.5mm. There is also an onboard potentiometer to adjust the sensitivity.
TCRT5000 Sensor Pinout
This sensor has 4 pins:
- VCC: Module power supply – 5 V
- GND: Ground
- DOUT: Digital output data to the microcontroller
- AOUT: Analog output data to the microcontroller
You can see pinout of this module in the image below.

// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// print out the value you read:
Serial.println(sensorValue);
delay(100)
}
After running the code, you will see the following image in the serial output.
