Double phototransistor detectors, can determine the direction of rotation On-board LED indicators Grove Interface, easy to use Automotive optical sensors The Grove Optical Rotary E ncoder (TCUT1600X01) is a transmissive sensor that includes an infrared emitter and two phototransistor detectors. Usually, the infrared emitter emits infrared rays, the phototransistor detectors receives the infrared rays, then the phototransistor is turned on, both of the output is High, the on-board LED indicators light up. When there is an obstacle blocking, the phototransistor can not receive the infrared rays, so the phototransistor will be turned off and both of the output will be Low, the on-board LED indicators fade away.
