Cytron Maker Reflect Reflectance Sensor

Description Cytron Maker Reflect Reflectance Sensor Features a tiny reflectance sensor This sensor is used in line following robot Used in various kinds of applications Fits easily in the tightest space The Cytron Maker Reflect Reflectance Sensor is a tiny simplifying IR reflectance sensor for beginners. It 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 line following robot as the white surfaces reflect more IR than black surfaces. However, it is not limited to line follower, there are much more application which can utilize the Maker Reflect. Eg.: Edge/Border sensor in Sumo robot, wall sensor in maze solving robot, short distance object detector (presence sensor), sensor for rotary wheel encoder...etc. This tiny sensor can be easily fitted in the
