This is an Infrared based sensor that can be used in detecting obstacles located in range of 2-30 cm



Description Transmitter launch a certain frequency infrared, when meet obstacle in the detection direction, the infrared receiver is reflected back by the receiver tube, after processing through the comparator circuit, the green indicator light will illuminate while the signal output interface output digital signal (a low-level signal) can be adjusted via potentiometer. Specifications: The module detects the distance 2 ~ 30cm, detection angle 35 °, The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay It uses a stable comparator which is LM393 The module is supplied with 3-5V DC power OUT : digital output interfaces (0 and 1); Getting started with the Obstacle Infrared Sensor module The device consists of an Infrared Transmitter, an Infrared Detector, and support circuitry. It only requires three connections. When it detects an obstacle within range it will send an output low. Hardware required Obstacle Infrared Sensor module Arduino UNO Jumper wires Obstacle Infrared Sensor module Pin Outs Connecting the Hardware Use the picture below. It only requires three wires. Copy, Paste and Upload the Sample Sketch // IR Obstacle Collision Detection Module // Henry’s Bench int LED = 13; // Use the onboard Uno LED int isObstaclePin = 7; // This is our input pin int isObstacle = HIGH; // HIGH MEANS NO OBSTACLE void setup() { pinMode(LED, OUTPUT); pinMode(isObstaclePin, INPUT); Serial.begin(9600); } void loop() { isObstacle = digitalRead(isObstaclePin); if (isObstacle == LOW){ Serial.println(“OBSTACLE!!, OBSTACLE!!”); digitalWrite(LED, HIGH); } else{ Serial.println(“clear”); digitalWrite(LED, LOW); } delay(200); } Test the Tutorial Sketch Move your hand towards the Obstacle Infrared Sensor module . Open your serial monitor and vary the distance of your hand while viewing the serial monitor. The output should look like the picture below: Package includes: 1×IR Infrared Obstacle Avoidance Sensor Module
