Need some guidance with telemetry.

Electronic projects that are either related to the firmwares for the 9x, or simply great for radio control applications.

Need some guidance with telemetry.

Post by Rad » Thu May 05, 2022 6:00 am

Hello guys, I am in the early stages of building my first RC Boat, a tug. This time I want to do something new, something that I have never done before, and that is telemetry.

I have been googling and youtubing but I have loads of info, but I feel most of it might be outdated. I mean, I have seen a lot of Frsky sensors piggytailed and also something similar with flysky. But at the other hand as you all know, the RC world has improved quite a lot, so it seems there are some sort of all in one boards for drones and planes that seem to have everything included. Am I right?

The thing is, I believe I need the following for my boat:
Temperature sensor for the motor,
Gps coordinates/compass, in case it sails too far away in the local lake here,
Battery level in the model.
Speed? It would not be a must but it is cool to have.

I think this boat cannot be SBUS, I am planning to connect several things like a benedini sound and lights board, smoke machine and some moving parts like anchor, radar and so on.

I am using a 9xtreme with multiprotocol module. So... what do you recommend me? It does not need to be super high quality long range tech, better if it is low budget.

Thanks in advance!

I use FrSky telemetry, mainly SPort (Smart Port). These "daisy chain" together. There is a sensor that will give battery pack voltage and current, together with two temperature sensors, and a GPS sensor that provides position, course and speed.

The difficult we do immediately,

Jesus, yes, I mean "Daisy chain" not piggytail, lol.
Well, I guess if you use that Frsky tech, that would be my way to go too.
I need 8 channels so I'd need a Frsky X8R receiver like this one The GPS sensor, like this one But the 3 in 1 sensor with battery voltage current and temperature sensors I cannot find it. Do you have a link or a name for it?

I also wonder if those sensors will work with something like this:

I'd love to fit something like that. I have seen an smaller version which is super cool too: https://github.com/TheDIYGuy999/Rc_Engi ... nb1yK54Jgo

thanks!

Correct for the X8R and GPS sensor.
I found the voltage/current/temperature sensor here: https://www.t9hobbysport.com/frsky-fas100-adv. I believe it is fairly new, I had not seen it before.

I don't know if the sound and display will work.

Hi Mike, while looking for those parts as cheap as possible I found this:

It seems very interesting, all in one sensor, cheaper and DIY, which is always cool. I think I will try to make one, it looks easy.

But it made me think one thing, do you know any DIY receiver wich supports the Frsky sensors? I might make my own receiver, each coin counts.
If I am not mistaken I remember Joao made some of his own receivers, but I don't remember which protocol or channels.

You should also check out OpenXSensor. Open source telemetry solution for FrSky, Graupner Hott, MPX and Jeti.

Can do:
GPS
Current
Voltage
Altitude
Pressure
