Key Features
- Reliable Object Detection: Uses infrared reflection principle - the IR LED emits light, and the receiver detects reflected signals when an object enters the detection zone
- Adjustable Detection Range: Onboard potentiometer lets you fine-tune the sensing distance from approximately 2 cm to 30 cm to match your application
- Clean Digital Output: Built-in LM393 comparator provides a crisp HIGH/LOW signal - no analog-to-digital conversion needed for basic detection tasks
- Dual Indicator LEDs: Power LED confirms the module is active; detection LED lights up when an object is detected, making calibration and debugging effortless
- Wide Voltage Compatibility: Operates on both 3.3V and 5V logic, ensuring seamless integration with Arduino, ESP32, Raspberry Pi, and other platforms
- Compact & Mountable: Small PCB footprint with an M3 mounting hole for easy and secure installation on robots, chassis, and enclosures
- Fast Response: Sub-2ms response time ensures real-time detection suitable for moving objects and dynamic environments
- Low Power Consumption: Draws minimal current, making it suitable for battery-powered and portable applications

How It Works
The IR Proximity Sensor operates on the principle of infrared light reflection. The onboard IR LED continuously emits infrared light (invisible to the human eye at 940 nm). When an object comes within the detection range, the infrared light bounces off the object's surface and is picked up by the photodiode receiver. The LM393 comparator then processes this signal against a threshold set by the potentiometer - if the reflected signal is strong enough (object is close enough), the output pin goes LOW (active low), and the detection LED illuminates. When the object moves away, the output returns to HIGH. This simple yet effective mechanism makes the sensor perfect for presence detection, obstacle avoidance, and counting applications.
