INTRODUCTION

This adjustable infrared sensor features a high-sensitivity photo reflector to perform distance detection functions, ranging from 3cm to 40cm. When the infrared light emitted by the emitter gets reflected on a surface that blocked it, the phototransistor can pick up the signal for distance calculation. Also, a potentiometer for adjustment is arranged for easy and clear use. Compared with a regular infrared sensor switch, it has advantages in distance, low interference by visible light, affordable, easy to assemble, easy to use, and can be widely used in robot obstacle avoidance, assembly lines, and many other occasions.

The obstacle detection distance can be adjusted with a potentiometer in the copper screw, once done adjusting(e.g. max 60cm), the sensor will output low flat within the effective distance (e.g. obstructions at 40cm & 10cm ) to the microcontroller.
