Hello Go Kart Enthusiasts,

I am a high school student in an engineering class, where we are currently constructing an electric go kart from the ground up. For a research project, I am researching electric telemetry systems(systems the remotely monitor the conditions of the car) and am trying to build one for the car. I have no real experience in mechanical or electrical construction, and would like to learn more. But for now, I have no knowledge in order to move forward with my project. Through my research I have found a telemetry system used for remote control cars made by a company called "Spektrum", who specializes in RC car parts. I have inserted a link to the product below. Could this product be used for a full sized go kart? If so, have any of you had experience with this product or my project in electric telemetry for go karts in general? Any help is appreciated. Thank you.

you're trying to build one?

GOOD!

it's not rocket science actually, you'll only need a handfull of sensors really and a way to read them.
You want to read the battery temp? well a tempsensor will be needed..
motor temp as well? add another.
Need to know current battery voltage? a voltage signal
current drawn? add an ampmeter..
Need rpm...? you get the idea.

all that can be bought or made for cheap (within some limitations of course)
some things you don't even need (like some motors do come with a tempsensor installed already.. you only need to read it)

Find the sensors (concentrate on arduino 6 compatibles) you'd need on the internet
most shops provide detailed instructions on how to use them, some provide sample code..
read all that you can of those samples and setup instructions

you'll quickly get the idea what they do, how they work and how to make your own small telemetry system
you can add a display or a bluetooth module to use your phone for loging and display;
possibilities are endless.

Buy what you need, and what's in the budget and you'll be fine.

Again, it needs some reading, some understanding and a bit of trial and error of course...
but in the end it's certainly no rocket science,
it's easy once you got into it.
Also, you've learned something usefull, you have indeed made it yourself and you have the best matching telemetry system for the project with the most advanced features you can think of and not even spent a lot!
And if you're missing a feature.. you now know how to quickly add it as well :D
by maybe just adding another sensor or some code changes...

I'm sure you'll be able to make one yourself..
but in case you do not feel like it.
Make sure the telemtrie system you have in mind is capable of reading the power of the motor and batteries
(there's no point in buying a system that craps out at 30Amps if your motor draws 120 or more;)) much less reading the voltage of a 96V batpack if the module only allows 48V max.

rpm, temp are universal of course..
and speed is just a matter of calculation
(motor rpm and gear ratio with wheel circumference... see one sensor less to care about ;))
but of course a wheelrpm sensor and the wheelcircumference adds a speedsensor just with one more sensor and three more lines of code ;)

PS check www.robotshop.com for example to get an idea of what sensor you could play around with,
from gyroscopes and acceleration sensors, to tilt and force sensors there's one for nearly everything you could think of.
