Grove - Optical Rotary Encoder L1-Digital Technologies-L2-Storage & Furniture-L3-Robotics Furniture and a powder-coated aluminium frameThe Grove Optical Rotary Encoder 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 outputs are High, the on board LED indicators light up. When there is an obstacle blocking, the phototransistor cannot receive the infrared rays, so the phototransistor will
