Is there a tilt angle sensor for two axes?

Question

Arduino

The mast with the antenna is set on extremely unstable ground. It is necessary to read the position (tilt) of the mast in degrees along two axes. Well, put it on a bus ... or on a network ... and feed it through the same wire. Tightness and -40 degrees overboard. The budget is extremely limited!

Answer 1

Well , something like that with a harness from a microcontroller and POE

Answer 2

It is not said about the requirements for accuracy and speed of removal.
Assemble a pendulum out of shit and sticks, read the position with two angular encoders (whatever, optical or magnetic, this is already to your taste and budget), so that the vibrations decay faster, put the blades (perpendicular to the plane of rotation of each plate is lighter and more area or on the pendulum itself with a cross ) to slow down on the air

Answer 3

A digital accelerometer, there are a lot of them for a different number of axes with industrial t... and with such consumption that, if you wish, you can even put your device on battery power.
We received the data, converted the accelerations to degrees and sent it to the right place.
As for the accuracy - you can see for an assessment the accuracy with which the same phone measures the angle, i.e. degrees, and even their shares, if desired, you can catch.
Tightness is ensured by varnish, or even by filling with a compound.

Answer 4

The mast with the antenna is set on extremely unstable ground.

3 braces?

Well, something with a microcontroller and POE harness ..... If you don’t like this gyroscope ...

And why drag a whole gyroscope if an accelerometer is enough? Or not?
If so, then the finished module can cost about 100 green ones: https://ru.mouser.com/ProductDetail/Analog-Devices...
Well, or do it yourself, which should not be very tricky for a radio amateur: https://ru. mouser.com/Sensors/Motion-Position-Sens...

Answer 5

In order not to collective farm yourself, you can find a lot of ready-made solutions on the Internet. Google towards the roll sensor . These are placed, for example, on poles and pipe racks with road signs.
