    1. Function introduce

    DH-SENSOR with a double hall sensor in the housing, detect the cycling of the bike. There are 12 magnets in the disc.DH-SENSOR will have higher precision than those with 5 magnets and the range sensor will be farther than those with 12 magnets.

    When the pedals go ahead, the sensor will output the pulse signal, the LED the low potential (There is no pulse signal), so the LED won’t flash. The convenience of detecting whether the sensor work well or not by the customers.

    2. Size & material

    PC shell is very good oxidation stability and aging characteristics.
