The Grove - Optical Rotary Encoder(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.
You can use this sensor as a rotary encoder to detect the speed or rotation, and thanks to the two phototransistor detectors, you even can detect the rotation direction.
Note
We've Released the Grove Selection Guide and hope to help you find the Grove suit you best.
