FrSky Hall RPM ADV Sensor – Magnetic RPM Telemetry, FBUS & Smart Port

The FrSky Hall RPM ADV sensor provides accurate rotational speed measurement using a magnetic pickup system, making it ideal for helicopters and rotating assemblies where direct shaft sensing is needed.

Part of the ADV sensor series, it supports both FBUS and Smart Port (S.Port) for seamless integration into modern FrSky telemetry systems.

Install the included magnet on a rotating component, position the sensor nearby, and get real-time RPM telemetry directly on your radio.
