Futaba FUSBS-01A S.BUS Altitude Sensor (Barometric Vario Module)  [FUSBS-01A]

Overview of S.BUS altitude sensing

This Futaba FUSBS-01A S.BUS sensor is an RC-scale accessory that measures atmospheric pressure to provide barometric altitude and vertical speed (vario) data over the S.BUS telemetry link. It is intended to integrate with S.BUS-capable receivers and telemetry systems to supply altitude-related telemetry for model aircraft and other RC models that use barometric data for trimming or logging.

Installation is straightforward for experienced hobbyists: connect the module to the S.BUS bus or an S.BUS-compatible receiver port and allow the system to recognize the sensor as part of the telemetry chain. In operation the sensor reports pressure-derived altitude and climb/descent rate, which can be used alongside other flight data to refine trim, set trim points, or record performance during testing flights.

When considering this accessory, confirm your receiver or telemetry device supports S.BUS sensor inputs and barometric telemetry. The module is described as an atmospheric pressure vario meter; detailed electrical and mechanical specifications should be referenced from Futaba documentation if precise mounting or power details are required.
