The FrSky HALL RPM Sensor ADV is a compact, high-speed rotational speed sensor designed for monitoring RPM in RC aircraft and other compatible model applications. As part of the FrSky ADVANCE (ADV) sensor range, it supports both FBUS and S.Port protocols, allowing RPM telemetry to be transmitted directly to compatible FrSky receivers and radios.

The Hall-effect sensor measures rotational speeds from 400 to 60,000 RPM, making it suitable for a wide range of applications including electric motors, engines and other rotating components.

When connected directly to a receiver's S.Port/FBUS port, the sensor can transmit RPM telemetry for display on a compatible FrSky radio. Alternatively, the sensor can be switched to PWM mode, allowing the rotation signal to be passed to a compatible device port that supports RPM calculation.

The supplied magnet is designed to work with the Hall sensor to detect rotation, while the extremely compact 2.5g sensor makes it suitable for installations where space and weight are important considerations.

Product Summary

The FrSky HALL RPM Sensor ADV provides accurate rotational speed monitoring across an impressive 400–60,000 RPM range. Using Hall-effect sensing technology and the supplied magnet, it can provide real-time RPM information through compatible FrSky telemetry systems.

The sensor can connect directly to an S.Port/FBUS-compatible receiver for telemetry transmission to a compatible radio, or it can operate in PWM mode for use with devices capable of calculating RPM from the supplied rotation signal.

At only 2.5g, the sensor is an excellent choice for lightweight and space-conscious RC aircraft installations.
