A set of drive reducing gear is three gear whells of the same size with reflective surface areas. Reflective surface areas of the central gear wheel reflect light when rotated. These light pulses are captured by a photosensitive diode; it converts them into electrical ones and transmits them to the board. By the number of pulses received, the board determines when the engine needs to be stopped.
