How to use :
1. First connect the sensor and wiring table.
2. When the sensor body close to the proximity switch when the light sensor (sensing distance is within the 5MM), indicating a signal input, a signal is received tachometer will show the speed value per minute.
3. We then turn the motor, when the magnet close to the Hall sensor, indicator lights, tachometer receives a signal sent is displayed.
