OpenXsensor
Posted: 04 Jan 2020, 20:44
Has anyone else tried using the openXSensor library for Arduino type hardware to make bespoke telemetry sensors?
The openXsensor library is compatible with FrSky, Graupner & Jeti telemetry systems and can be used to make your own telemetry sensors units to monitor any combination of the following with the a small Arduino Pro Mini board and standard sensor hardware items:
Voltage (e.g. LiPo/individuals cells etc. via simple resistor dividers)
Current (e.g. Flight battery via Hall or very low resistance based sensors)
Altimeter/Variometer (via barometric pressure & temperature sensor)
GPS data (using standard commercial GPS antenna/module)
Airspeed (via pitot head & differential pressure sensor as used on say FrSky commercial units)
Motion (via 3 axis accelerometer/gyro and/or magnetometer)
Temperature (via thermistors)
RPM (via pulse generating sensor)
Flow (e.g. fuel via an impeller type pulse generating sensor)
Chris Bott did a couple of articles in RCM&E a few months ago & I have now successfully produced two different units.
One can measure 4S LiPo cell voltages, current up to 120A, plus Altimeter/Vario - the black unit.
The second does GPS & Altimeter/Vario - shown before heatshrink added. GPS is the square block at opposite end to the barometric sensor, both being above the small processor board.
Overall size of each unit is about 2” x 1” x 0.5” in old money.
The units are fairly easy to produce if you are handy with a small soldering iron & have a PC to run the Arduino software in order to compile & upload the required code to the processor board.
