【EXTENSIVE APPLICATIONS】: This 5Pcs IR infrared obstacle avoidance sensor module can be widely used for robot obstacle avoidance, obstacle avoidance car, assembly line, black and white line tracking and many other occasions 【MULTIPLE WORKING METHOD】: This IR infrared obstacle avoidance sensor module output port OUT can be directly connected to micro-controller IO port, which also can drive a 5V relay directly 【LOW NEGATIVE IMPACT】: The detection range of this IR photoelectric obstacle avoidance sensor can be adjusted with potentiometer, which has little interference, and this avoidance sensor module is easy to assemble 【ADJUSTABLE FUNCTION】: 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 level detection distance can be adjusted with potentiometer, clockwise to increase detection distance 【NOTE】: 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 detection range, Weight: 0.00661386786 Pounds, Manufacturer: Oumefar
