Reflection Sensor Obstacle Avoidance Sensor Light IR Infrared Sensor 5pcs Adjustable for IR Robot
Sensor module output port OUT can be directly connected to micro-controller IO port, also can drive a 5V relay directly.
It can be widely used for robot obstacle avoidance, obstacle avoidance car, assembly line, black and white line tracking and many other occasions.
When module detects obstacles ahead, the green indicator light on the circuit board is on and at the same time the OUT port outputs low ; detection distance can be adjusted with potentiometer, clockwise to increase detection distance;c
Active infrared reflection detecting sensor, so the target reflectivity and shape is the key of the detection range.Black color has the minimum detection range, white has the maximum; small objects have short detection range, large objects have long dete
The detection range of the sensor can be adjusted with potentiometer, little interference, easy assembly and use.
