8-Ch way Line Detection Tracking IR Infrared Sensor Module

The 8-Ch way Line Detection Tracking IR Infrared Sensor Module 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.

8-Ch way Line Detection Tracking IR Infrared Sensor Module determines whether there exists an object or not by the light intensity. It can easily identify black and white lines. 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.

This 8-Ch way Line Detection Tracking IR Infrared Sensor Module has 8 IR LED/phototransistor pairs mounted on a 0.375″ pitch, making it a great detector for a line-following robot. Each sensor provides a separate digital I/O-measurable output. This reflection sensor array is intended as a line sensor, but it can be used as a general-purpose proximity or reflection sensor. The module is a convenient carrier for eight IR emitter and receiver pairs evenly spaced at intervals of 0.375″ (9.525mm). The lower output voltage is an indication of greater reflection.

Each of the eight infrared reflectance sensors operates independently. Each sensor has a capacitor that is used to establish an RC timing circuit used to determine the amount of reflectance based on time.

8-Ch way Line Detection Tracking IR Infrared Sensor Module can be used with both 5V and 3.3V microcontrollers depending on a jumper setting. The board consumes about 100mA when active and the infrared LEDs can be powered off during idle times to conserve energy at about 10mA.
