Датчик оборотов Spirit

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: 3.3V - 15V

Brown wire: Ground (GND/-)

1 Wiring Example

Powering Lead with Red and Brown wires can be plugged to any free port with a BEC voltage. Signal Lead with Orange wire must be plugged always at the middle Pin of the ELE/PIT/AIL port (Spirit 1, Spirit Pro, Spirit 2, Spirit GT) or EXT/RPM/E2 port (Spirit RS and Spirit GTR).

2 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.

3 Governor Settings

When sensor is connected you can optionally use Spirit Governor. Please set the Sensor Divider parameter so that the value will represent count of the active magnets. Usually it is 1 or 2 magnets.
