Maker Reflect is a tiny reflectance sensor that consists of an infrared (IR) LED that transmits IR light onto a surface and a phototransistor measures how much light is reflected back. The output is in analog voltage. The more IR light is sensed by the phototransistor, the lower the voltage. Typically, this sensor is used in a line following robot as white surfaces reflect more IR than black surfaces. However, it is not limited to line followers; there are many more applications that can utilize the Maker Reflect, such as an edge/border sensor in a Sumo robot, wall sensor in a maze-solving robot, short-distance object detector (presence sensor), a sensor for a rotary wheel encoder, and more.
Measuring only (L)18.1mm x (W)8.4mm x (H)4.2mm (excluding the header pin), this tiny sensor can be easily fitted in the tightest space available on your robot. The sensor is purposely designed with the mounting hole at the center so that it can be at the front-most position, which is especially important in a Sumo robot.
Applications:
- Line Following Robot
- Sumo Robot
- Wall Following Robot
- Short Distance Object Sensing
- Sensor for Printed Rotary Wheel Encoder
