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.

Power

The typical voltage of TCUT1600X01 is 5V, so we use the MP3120 current mode step-up converter to provide a stable 5V. The input of MP3120 ranges from 0.8V to 5V, so you can use this module with your Arduino both in 3.3V and 5V.

When the phototransistor detectors receive the infrared signal, the output should be High, and when the obstacle blocks the infrared, the OUT1 and OUIT2 should be Low. However due to the leakage current, it won’t be 0V. The leakage voltage varies with the input voltage.

Directional Detection

tip

Thanks to the two phototransistor detectors, we can detect the moving direction. If the obstacle moves from the left to right, The output states change should be **11 --> 01 --> 00 --> 10**; in the same way, if the obstacle moves from the right to left, it should be **11 --> 10 --> 00 -->01**.
