Futaba FUSBS-01A Atmospheric Pressure Vario Meter for S.BUS  [FUSBS-01A]

S.BUS altitude and vario function explained

This Futaba FUSBS-01A S.BUS sensor converts atmospheric pressure into barometric altitude and vertical speed readings and sends that information over the S.BUS telemetry link. It is suitable for use with S.BUS-enabled receivers and telemetry displays on model aircraft and other radio-controlled models that use pressure data for flight monitoring.

Fitting is typically done by attaching the module to the S.BUS bus or plugging into an S.BUS port on a compatible receiver; the telemetry system will list the sensor and begin passing altitude and climb/descent figures to your transmitter or logger.

Ensure your receiver and transmitter support S.BUS telemetry and barometric sensors before installation. For precise mounting, power, or mechanical guidance, refer to the official Futaba documentation.
