Maxmoral 2-Pack Intelligent Obstacle Avoidance Sensor for Arduino DIY Smart Car Robot,Photoelectric Reflection Sensor IR Infrared Module

Module description: Operating voltage: 3.3V-5V Effective Distance range: 2 ~ 30cm Circuit board size: 3.2x1.4cm Detection angle: 35 degrees The sensor module light is adaptable to the environment, it has a pair of infrared transmitting and receiving tube, tube infrared emitting 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 and output digital signal (a low level signal), can be adjusted through the potentiometer knob detection distance. Description of module parameters: 1.when the signal module detects obstacles ahead, 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 ~ 30 cm, 35 degree Angle detection, detection distance can be adjusted through the potentiometer, clockwise adjust potentiometer, detection distance increases; Counterclockwise potentiometer reduces detection distance; 2. Sensor active infrared reflection detection, so target reflectivity and shape are the key to detection distance. The black detection distance is the smallest and the white is the largest. Small objects have small distances and large areas have large distances; 3. The output port OUT sensor module can be directly connected to the IO port of the single-chip microcomputer or directly drive a 5V relay; Connection mode: VCC-VCC; GND-GND; OUT-IO; 4. The comparator adopts LM393 and works stably; 5.3mm screw hole for easy fixation and installation. Module Interface Description: 1.VCC external 3.3V-5V voltage (can be directly connected to 5V single-chip microcomputer and 3.3V single-chip microcomputer) 2.GND external to GND 3.OUT panel digital output interface (0 and 1)
