20pcs Obstacle Avoidance Reflection Photoelectric Sensor Infrared Alarm Module

Features Module description The sensor module light is adaptable to the environment it has a pair of infrared transmitting and receiving tube tube infrared emit a certain frequency when detecting direction meet with obstacles reflecting surface reflected infrared receiving tube after the comparator circuit processing green indicator will light up at the same time signal output interface to output digital signal a low level signal can be through the potentiometer knob adjust the detection distance effective distance range 2 30cm working voltage is 3 3V to 5V The sensor detection range can be through the potentiometer to adjust and have small interference easy to assemble easy to use etc can be widely used in robot obstacle avoidance obstacle avoidance car line count and black and white line tracking and so on many occasions Module Parameter 1 When the module detects obstacles in front of the signal the green indicator on the circuit board light level and at the same time the OUT port output low level signal the detection module from 2 30cm 35detection Angle test distance can be adjusted through the potentiometer adjustable potentiometer clockwise the detection distance increases Counter clockwise tuning potentiometer detection distance is reduced 2 Sensors active infrared reflection detection therefore the reflectivity and shape of the target is the key of the detection range White one black detection range minimum maximum Small area of
