TCRT5000 Infrared Sensor

TCRT5000 Sensor Overview

The **TCRT5000** is an infrared sensor that combines an infrared emitter (LED) and a phototransistor in a single package. It is commonly used for proximity sensing, line-following robots, and other applications that require object detection or reflective surface detection. This sensor is capable of detecting objects within a specific range using reflected infrared light.

Pinout of TCRT5000

The TCRT5000 has 3 pins, each with a specific function that allows you to interface with the sensor. Below is the pinout of the TCRT5000 infrared sensor:

Working Principle

The **TCRT5000** works by emitting infrared light from the LED, which is then reflected by an object back toward the phototransistor. When the amount of reflected infrared light hits the phototransistor, it activates the transistor, causing it to change its state. The output pin then provides either a high or low signal, depending on the presence and proximity of the object. This output signal can be read by a microcontroller, such as an Arduino, for further processing.

Applications

• Used in line-following robots for detecting lines or edges.
• Used for proximity sensing in various robotic applications.
• Can be used for object detection in automated systems.
• Ideal for obstacle detection in security systems.
• Used in encoders to detect the position of rotating parts.
