4-channel IR Tracking Sensor Unit

Remark: The PCB color may vary

Description:

This 4-channel IR tacking module can be used as the sensing device for robotic chassis to avoid obstacles, detecting distance and line patrol. Sensing distance (1mm to 6cm) can be adjusted by turning the potentiometer.The shorter the distance, the better the performance.

Infrared emission phototube of each channel sensor is giving out infra-red, when infrared ray is not reflected back or intensity is not enough, the infrared receiving phototube is off, TTL output high level, the diode light is off; When an object is in the range of detection, infrared ray is reflected back or intensity is enough, TTL output is low level, the diode light is on
