2-Channel Velocity Measurement Kit

Details

This Kit helps you monitoring the velocity speed of motors, it uses the sensor HC-020 to sense the rotation of circular grid board, and thus output square waves. So users can calculate the rotation velocity or speed via these outputs frequency. There are 20 grids on the circular grid board, so each rising/falling edge standing an angle: 360/20= 18 degrees. Please uncover the yellow protect paper before your using.
