4) With a RESET button on the board for resetting, and positioning holes on the board for easy assembly
5) Supply Voltage: 5V; PCB Dimensions: 124mm x 30mm
Technical Details
Introduction
The TCRT5000 infrared photoelectric switch adopts a high transmit power infrared photodiode and a highly sensitive phototransistor. It works by applying the principle of objects' reflecting IR light – the light is emitted, then reflected, and sensed by the synchronous circuit. Then it determines whether there exists an object or not by the light intensity. It can easily identify black and white lines. In other words, the different conduction levels of the phototransistor when it passes over black and white lines can generate different output voltages. Therefore, all we need to do is to collect data by the AD converter on the STM8S105C4 and then send the data to the master control board via I2C communication.
This module is an infrared tracking sensor one that uses a TRT5000 sensor. The blue LED of TRT5000 is the emission tube and after electrified it emits infrared light invisible to human eye. The black part of the sensor is for receiving; the resistance of the resistor inside changes with the infrared light received.
Note: When the module is working, it's normal to get heated And this module is not compatible with Raspberry Pi.
