Infrared Obstacle Avoidance Sensor — IR Photoelectric Module
This infrared obstacle sensor emits IR light and detects the reflected signal from objects within 2–40cm, outputting a digital LOW when an obstacle is detected and HIGH when clear. An onboard potentiometer sets the detection distance, and the LM393 comparator delivers a clean TTL signal with over 15mA drive capacity. The 3.3V–5V supply range connects directly to Arduino, ESP32, and Raspberry Pi GPIO without a level shifter.
- 2cm–40cm detection range — potentiometer adjustable
- Digital output — LOW on detection, HIGH when clear
- LM393 comparator — clean TTL signal, active low
- 3.3V–5V supply — direct GPIO connection
- Onboard indicator LED — visual detection feedback
Best for
Robot obstacle avoidance, conveyor belt item detection, automatic hand sanitiser triggers, bin lid sensors, edge detection for line followers, and touchless switch applications.
