₹25.96 incl. GST (₹22.00 + GST)
The Infrared Obstacle Avoidance IR Sensor Module is a compact sensor for detecting nearby objects using reflected infrared light. It operates from 3.3–5 V and provides an active-low digital output through its 3-pin interface. The detection range can be adjusted from approximately 2 cm to 80 cm using the onboard preset. It also features an indicator LED and is ideal for Arduino, ESP32, robotics, obstacle avoidance, and automation projects.
Product Description
The Infrared Obstacle Avoidance IR Sensor Module is a compact and easy-to-use sensor designed for detecting nearby objects using infrared light. It consists of an IR transmitter and receiver pair that detects reflected infrared light when an obstacle is present. An onboard comparator processes the received signal and provides a digital output.
The module operates from 3.3 V to 5 V and features a simple 3-pin interface: VCC, GND, and OUT. When an obstacle is detected, the output provides an active-low signal, making it easy to interface with Arduino, ESP32, Raspberry Pi, and other microcontrollers.
An onboard preset adjustment knob allows the detection distance to be fine-tuned, with an effective sensing range of approximately 2 cm to 80 cm. A built-in indicator LED provides visual confirmation when an obstacle is detected.

Working Principle
The IR transmitter continuously emits infrared light. When the IR light encounters an obstacle, part of the light is reflected toward the IR receiver. The onboard comparator detects this reflected signal and changes the output state.
When an obstacle is detected, the OUT pin produces a LOW-level signal and the onboard indicator LED lights up. The detection distance can be adjusted using the onboard preset knob.
