Hello,
I am working on developing a data logger for a variety of electric mobility devices. These devices operate at various voltages and currents ranging from 12V - 48V (DC) and 60A - 200A.
The device I would like to build would log the speed, voltage and current over some interval. The application would allow for either an inline ammeter or a amp clamp. My question is, what can be used to measure 200A and communicate that to an arduino?
Hi @willkozub,
have a look here Measuring 200A - 400A AC current using arduino. - Using Arduino / Sensors - Arduino Forum if it is AC!
Good luck!
Sorry, should have mentioned that, it is DC.
Seems like walmart offers devices for DC
But be careful with cheap solutions!
Better use one of the commercially available solutions like this https://www.peaktech.de/uk/Products/Electrical-engineering/Current-clamp-multimeters/True-RMS-current-clamps/
Using Bluetooth as the interface to Arduino hardware is a nice way not to get into trouble with electrical safety at the Arduino side. 200 amps can be very dangerous if they are short-circuited, not only for the electronics ...
If you do something wrong, just picture an EV fire in your pants.
