FrSky VARI-H Smart Port Telemetry Variometer Sensor (High Precision Version)

FrSKY High Precision Vario Sensor monitors atmospheric pressure and reports altitude and changes in pressure, indicating lift which is invaluable if you want to catch thermals with your RC plane.

The FrSky High Precision Variometer measures the rate of change of altitude by detecting the change in air pressure (static pressure) as altitude changes. When used with the FrSky Taranis transmitter you can create a true glider vario with tones that indicate lift and sink, a feature usually costing several hundred dollars for other radio systems.

Features:

• Capable of connecting directly to the telemetry receivers without the sensor hub
• Backward compatibility with existing sensor hub and sensors, also compatible with new generation Smart Port enabled sensors
• Smart Port enabled, realizing two-way full duplex transmission
