IR Sensor

Digital Infrared Obstacle Avoidance Sensor

This compact infrared sensor module integrates an IR transmitter and receiver pair to accurately detect proximity and obstacles. Utilizing an onboard LM393 comparator, it provides a clean digital output when an object breaks the reflective threshold, offering easily adjustable sensitivity via a built-in precision potentiometer.

• Detection Range: 2cm to 30cm (Adjustable)
• Operating Voltage: 3.3V to 5V DC
• Detection Angle: ~35 Degrees
• Common Use Case: Autonomous line-following robots, automated dispensing systems, and non-contact limit switches.
