30Pcs 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 Lees meer over de 30Pcs Obstacle Avoidance Reflection Photoelectric Sensor Infrared Alarm Module van huismerk in de productgroep elektronica
