TCRT5000 IR Sensor Module

is a compact and versatile infrared reflective sensor module designed for detecting objects, surface colors, and changes in reflected infrared light. It uses an infrared LED as the transmitter and a phototransistor as the receiver to detect the reflection of infrared light from nearby surfaces. This makes it especially useful for line-following robots, object detection, proximity sensing, and surface recognition applications.

The module typically operates with a 3.3V to 5V DC power supply and provides a digital output for easy connection to microcontrollers. Many versions also provide an analog output for applications that require more detailed sensing information. An onboard potentiometer allows the sensitivity or detection threshold to be adjusted according to the application and surrounding conditions. 

The TCRT5000 IR Sensor Module is widely used for detecting differences between black and white surfaces, making it an excellent choice for line-following robots and tracking systems. It can also be used for short-range object detection, counting applications, encoder systems, and automation projects. Its compact size and simple interface make it easy to integrate with Arduino, ESP32, Raspberry Pi, and other microcontroller-based systems.
