This small VARIO + Altimeter unit has the Measurement Specialties MS5611 absolute pressure sensor integrated with the SBUS2 protocol in a miniature and cost effective solution.
The MS5611 sensor is one of the most accurate pressure sensors available, and combined with Kalman filtering as well as moving-average filtering, an extremely high resolution and precision has been achieved. Utilizing the Futaba SBUS2 sensor readout ability to show CENTIMETER precision, it takes VARIO to a whole new level. Even with filter settings to instant readout of altitude changes, the sensor noise is below ±10 cm. The system lag for sudden altitude changes is kept below 250 ms, showing the full advantage of using Kalman filtering and the great performance of the Futaba SBUS2 telemetry.
