3pin IR Infrared Obstacle Avoidance Sensor Module

Smart Electronic Infrared IR Infrared Avoidance Sensor Module for Arduino Smart Car 3-Wire Robot Reflective photocell infrared obstacle module, obstacle avoidance trolley, adjustable black and white line distance recognition sensorname: infrared obstacle avoidance module (adjustable from 2-30 cm.) Dimensions: 45.50 mm. * 14.10 mm. * 8.50 mm. (Length x Width x Height) Color: Blue product weight: 3.42g (with packing) Details: Module The sensor has strong adaptability to ambient light and has dual infrared emitting and receiving lamps. The lamp emits a certain frequency of infrared radiation. when the detection direction encounters obstacles (surface reflection), infrared radiation will be reflected from the receiver tube after processing, the green light comparator circuit will shine, even if the digital signal output interface (0V signal low) through the potentiometer knob to Adjustable detection range, effective range 2~30cm, working voltage3.3V -5V. Sensor detection distance can be adjusted by potentiometer. It has the features of small interference, easy installation and easy operation. It can be widely used in many situations, such as robot obstacle avoidance, car obstacle avoidance, pipeline calculation and black and white line detection.Performance: 1. When there is no obstacle signal in front. of the module output port will continuously discharge a high level (5V) When the module detects an obstacle signal in front, the green indicator on the circuit board will light up, and the output port will continue to emit a low signal (0V), the module sensing distance 2 ~ 30cm, detection angle 35°, sensing distance The detector can be adjusted by potentiometer, potentiometer clockwise, increasing distance detection; Counterclockwise meter to reduce detection distance.2. Infrared reflection sensor is active, so the reflection and shape of the target is the key to detecting the distance. the smallest, the highest black, white detection range; Small area of object distance, large area distance.3. The output port of the sensor module output can be directly connected to the IO port of the microcontroller directly drive the 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO4, compare with LM393, stable.5 Module can use 3.3V-5V DC power supply. When power on, the indicator light is red, instructions for use. Work: 1.VCC external voltage3.3V-5V (Can be directly connected to 5V or 3.3V single chip microcontroller) 2.GND GND3. External (0 and 1) Package: 1 x 3pin IR sensor module Avoid infrared clogging
