Welcome to the OpenIVario Wiki!
At the begin i want to show a short Demo of the variometer, including sensitivity and full sunlight test, followed by an explanation of various setup options and how to use.
- Quick Demo on YouTube
- Vario Sensitivity Test
- Basic Function Demo
- Full Sunlight test
- Basic Vario Setup MC, QNH, Ballast
- Airfield Elevation and Vario Setup
- Bluetooth, Audio and Polar Setup
- Flap (WK) Indicator Setup
- Vario System Setup
- Setup XCSoar to connect with Vario
The project is dedicated to my new flight computer development using ESP32 WROOM development board plus modern sensors such as BMP280, DS1820b, MP5004DP, and colored sunlight readable display display. It delivers data in the well known and documented OperVario format to any flight computer running XC-Soar.
The design supports the follwing sensors:
- Outside Temperature
- Airspeed
- Variometer
- Barometric Altitude
The ESP32 module contains a bluetooth sender module, so we are able to transmit all data to XCSoar in 'OpenVario' format, so XCSoar can operate as full glide computer with TE-Vario, Barometric Altitude, Speed and more.
