Features:

Variometer Sensor for FrSky Telemetry System

The Variometer sensor calculates the altitude from atmospheric pressure. Atmospheric pressure will get lower as you
go up in altitude, using this the sensor will estimate the altitude. An exact display cannot be performed if atmospheric
if atmospheric pressure changes in weather.
The Variometer sensor also can output the Altitude Rate via DA port.
Altitude Rate formula: (Output DA Voltage - C1.65)/1.65= Altitude Rate speed/10.24.

There are two versions for the variometer sensors, one is normal precision, another is high precision.

This is the normal precision version.

I ordered the high precision version for extra money - and to be honest I don't need such accuracy and I'm not sure why people do.
Does anyone know why people need it more accurate than 1m ?
