IR sensor module detects obstacles using infrared light – perfect for Arduino, line-following robots, and automation systems Read more
The IR Sensor Module is a reliable and affordable solution for obstacle detection, line following, and proximity sensing. It works by emitting infrared light and detecting its reflection from nearby objects. This sensor outputs a digital signal that can be easily read by Arduino, ESP32, Raspberry Pi, or any other microcontroller.
Widely used in robotics, automation, and smart systems, it’s perfect for beginner and advanced projects involving collision detection, edge detection, or presence sensing.
Key Features:
Operating Voltage: 3.3V – 5V
Output: Digital (LOW when obstacle detected)
Adjustable sensitivity via onboard potentiometer
Detection range: 2cm – 30cm (approx.)
Infrared transmitter and receiver pair
Power and signal LEDs for status indication
Easy to connect with Arduino, ESP32, Raspberry Pi
Applications: Obstacle avoidance, line following, automation, smart toys
