Tutorial: How to Use the TCRT5000 Proximity Sensor

The TCRT5000 proximity sensor is an optical device that emits and receives infrared signals to detect objects up to 950mm. Ideal for Arduino projects where contactless distance detection is required.

What you need

• Arduino
• USB Cable
• Connect to PC
• Arduino IDE Software

Steps

1. Connect the sensor to the Arduino board using jumper wires, following the pinout table of the TCRT5000 module (VCC to 5V, GND to GND, OUT to a digital pin of the Arduino).
2. Open the Arduino IDE and create a new sketch.
3. Insert the provided code to read the state of the sensor’s output.
4. Compile and upload the program to the Arduino.
5. Check that the LED on the detector lights up when there are objects nearby.
6. Change the detection range by altering the pin values or signal strength.
7. Test different materials to see how the detector reacts.
8. Adapt the sketch to a specific project.

Example code

const int sensorPin = 2; // collega l'uscita del sensore al pin digitale 2
void setup() {
  pinMode(sensorPin, INPUT);
}
void loop() {
  if (digitalRead(sensorPin) == HIGH) { 
    Serial.println("Oggetto vicino");
  } else {
    Serial.println("Nessun oggetto");
  }
}

Mini project

Create a home security system that sends a notification when someone approaches a specific point. Use the TCRT5000 detector to sense movements and a WiFi or Ethernet module to send notifications.

Common mistakes

• Do not verify the correct power supply of the detector
• Use a detection range beyond 950mm
• Omit the GND connection
• Ignore the orientation of the detector relative to the object

Recommended accessories

• Arduino Uno R3
• ESP8266 WiFi Module
• 3D printer to build a protective case
• Various jumper connections

Frequently asked questions

Does the detector work only with Arduino?
No, it can be used with any microcontroller that supports digital signals.

What is the maximum detection distance?
Check the TCRT5000 sensor datasheet for the exact distance.
