IR Infrared Obstacle Avoidance Sensor Module – Adjustable Range Proximity Switch for Arduino & Smart Cars in Pakistan

Overview 

The IR Obstacle Avoidance Sensor Module is a versatile distance-sensing solution for short-range detection. It consists of an infrared transmitter and an infrared receiver pair. When the sensor detects an obstacle in its path, the green indicator LED lights up, and the OUT pin pulls LOW. Thanks to the onboard potentiometer, you can fine-tune the detection distance to suit your specific project—whether it’s a fast-moving robot car or a simple touchless switch.

Key Features

• Adjustable Detection: Use the onboard knob to set the detection range from 2cm to 30cm.

• Instant Digital Output: Logic-level output makes it 100% compatible with Arduino, Raspberry Pi, ESP32, and even simple Relay modules.

• 3-Pin Simplicity: Only requires VCC, GND, and a single Digital Input (OUT) pin.

• Wide Angle Sensing: Effective detection at a 35° angle, ensuring your robot sees what’s coming even from the side.

• Compact & Lightweight: Small enough to fit on the front bumper of any micro-robot.
