User Manual_SSP-DH Speed Sensor_TopEParts
1. Function Introduce
SSP-DH dual Hall sensor is a pedal assistant sensor adapted for quickly assembled electric bicycles, which can be mainly used for the signal of power assisting for the bike. Compared with SH-SENSOR, the DH-SENSOR equipped with a DIY disc of 12 magnets, offers higher accuracy and further detection distance which can reach 6mm.
SSP-DH sensor with dual Hall is more sensitive 2-3 times than that with the single Hall sensor.
When the pedal turns forwards, the sensor outputs a pulse signal and a red LED indicator flashes on the sensor.
When the pedal turns back, the sensor outputs a low-level signal, the red LED indicator is not lit. So that users can check any failure of the sensor.

3. Installation Instruction
Fix the sensor beside the frame of the bike, and put the disk through the pedal. To get a high sensitivity the magnetic dot of the disk must be faced with the cross mark and adjust angle trestle and sensor.
The effective sense distance of the speed sensor is 6 mm to the magnet. Install the speed sensor with ribbon tapes.
