TCRT5000 IR Sensor Module
TCRT5000 IR Sensor Module
The TCRT5000 IR Sensor Module is a compact, infrared-based proximity sensor module designed for detecting objects or obstacles in various applications. It is a popular choice among robotics, automation, and IoT enthusiasts due to its ease of use, high accuracy, and affordability.
The TCRT5000 IR Sensor Module is designed to detect objects or obstacles within a certain distance range by emitting infrared light and measuring the reflected light. When an object is within the detection range, the sensor outputs a digital signal indicating the presence or absence of the object.
The TCRT5000 IR Sensor Module is sensitive to ambient light conditions and may require additional shielding or filtering in bright environments.
The detection range may vary depending on the object's reflectivity, color, and surface texture.
Users should adjust the sensitivity potentiometer carefully to avoid false triggering or missed detections.
By leveraging the TCRT5000 IR Sensor Module's features and functionality, developers can create a wide range of innovative IoT projects and applications that require accurate and reliable object detection.

Overview
The TCRT5000 IR Sensor Module is a reflective infrared sensor module designed for obstacle detection, proximity sensing, and distance measurement applications. It operates by emitting infrared light and measuring the reflected light to detect objects. This module is widely used in robotics, automation, and IoT projects.
Pinout and Connection
The TCRT5000 IR Sensor Module has a 3-pin interface:
VCC: Connect to a 5V power supply
GND: Connect to ground
OUT: Connect to a digital input pin on a microcontroller or development board
Examples and Code
### Example 1: Basic Obstacle Detection using Arduino
In this example, we'll use the TCRT5000 IR Sensor Module to detect obstacles using an Arduino board.
Hardware
TCRT5000 IR Sensor Module
Arduino Uno or compatible board
Breadboard and jumper wires
Code
```c++
const int sensorPin = 2; // Connect OUT pin to digital pin 2
void setup() {
pinMode(sensorPin, INPUT);
Serial.begin(9600);
}
void loop() {
int sensorState = digitalRead(sensorPin);
if (sensorState == LOW) {
Serial.println("Obstacle detected!");
} else {
Serial.println("No obstacle detected.");
}
delay(50);
}
```
In this example, we read the output of the TCRT5000 IR Sensor Module using digital pin 2 on the Arduino board. If the output is LOW, it indicates an obstacle is detected, and we print a corresponding message to the serial monitor.
### Example 2: Distance Measurement using Raspberry Pi (Python)
In this example, we'll use the TCRT5000 IR Sensor Module to measure distance using a Raspberry Pi and Python.
Hardware
TCRT5000 IR Sensor Module
Raspberry Pi 3 or compatible board
Breadboard and jumper wires
Code
```python
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
sensorPin = 17 # Connect OUT pin to GPIO 17
def read_distance():
GPIO.setup(sensorPin, GPIO.IN)
start_time = time.time()
while GPIO.input(sensorPin) == GPIO.HIGH:
pass
end_time = time.time()
distance = (end_time - start_time) 34000 # Calculate distance in cm
return distance
while True:
distance = read_distance()
print("Distance: {:.2f} cm".format(distance))
time.sleep(0.1)
```
In this example, we use the Raspberry Pi's GPIO library to read the output of the TCRT5000 IR Sensor Module. We measure the time it takes for the output to go from HIGH to LOW, which is proportional to the distance of the object. We then calculate the distance in centimeters using the speed of light.
Note: These examples are for illustration purposes only and may require calibration and adjustments for specific use cases.
