This sensor is HALL type which senses RPM by motion of the rotating magnets. Usually 1 - 2 neodymium magnets are mounted on the fan of combustion helicopters with a Nitro motor.
- Wire layout
- Orange wire: RPM Output Signal
- Red wire: Ground
- Brown wire: 3.3V - 15V
Wiring Example
1 Magnet mounting
We highly recommend to orientate each magnet as Active for a proper operation. More magnets will result in a higher reading resolution thus increased readout precision.
2 Governor Settings
When sensor is connected, please set the Sensor Divider parameter so that the value will represent count of the active magnets. Usually it is 1 or 2 magnets.
