Reviews (2)

The basic concept of IR(infrared) obstacle detection is to transmit the IR signal(radiation) in a direction and a signal is received at the IR receiver when the IR radiation bounces back from a surface of the object.

Features:

There is an obstacle, the green indicator light on the circuit board
Digital output signal
Detection distance: 2 ~ 20cm
Detection angle: 35 ° Degree
Comparator chip: LM393
Adjustable detection distance range via potentiometer:
- Clockwise: Increase detection distance
- Counter-clockwise: Reduce detection distance

Specifications:

Working voltage: 3 - 5V DC
Output type: Digital switching output (0 and 1)
3mm screw holes for easy mounting
Board size: 3.2 x 1.4cm

Pin, Control Indicator	Description
Vcc	3.3 to 5 Vdc Supply Input
Gnd	Ground Input
Out	Output that goes low when obstacle is in range
Power LED	Illuminates when power is applied
Obstacle LED	Illuminates when obstacle is detected
Distance Adjust	Adjust detection distance. CCW decreases distance. CW increases distance.
IR Emitter	Infrared emitter LED
IR Receiver	Infrared receiver that receives signal transmitted by Infrared emitter.

Connect Detection Module to Arduino (Henry's Bench)

// IR Obstacle Collision Detection Module

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);
}

Move your hand towards the IR LEDs. As you near them, the Output LED on the module and the LED for pin 13 on your Arduino will illuminate. Open your serial monitor and vary the distance of your hand while viewing the serial monitor. The output should show "Clear" to "OBSTACLE!!, OBSTACLE!!".
