Elecrow Crowtail- IR Reflective Sensor 2.0 Module - 4-15mm Detection, 5V Digital Output
The Elecrow Crowtail IR Reflective Sensor 2.0 is a 5V digital output module designed for proximity and obstacle detection within a 4-15mm range, utilizing an RPR-220 reflective photosensor. It is compatible with Crowtail and standard 5V microcontroller systems like Arduino and Raspberry Pi for applications in robotics and automation.
Features
- Infrared reflective sensing with a 4-15mm effective detection range.
- Digital HIGH/LOW output signal for simple integration with microcontrollers.
- On-board potentiometer for precise sensitivity adjustment.
- Based on the reliable RPR-220 reflective photosensor module.
- Low power consumption, averaging ~15mA at 5V.

The Crowtail IR Reflective Sensor 2.0 operates on the principle of infrared light reflection. An internal IR LED emits light, which is then reflected by a nearby object and detected by the integrated RPR-220 phototransistor. The module’s comparator circuit outputs a digital logic HIGH when no reflection is detected (no obstacle) and switches to LOW when an object is present within the adjustable sensing window.
This sensor is engineered for stability and ease of use in embedded systems. The inclusion of a sensitivity-adjusting potentiometer allows fine-tuning for different surface reflectivities and environmental conditions, making it suitable for precise detection tasks. Its compact, board-mounted design integrates seamlessly into the Crowtail ecosystem and other 5V logic environments.
