Hi,
What components could I use to measure DC current anywhere up to 50amp?
I also want to measure DC voltage of two 12v batteries connected in series so just over 24v when fully charged.
This data I want to display on an LCD on an Arduino Uno.
Any advice would be appreciated!
Thanks
Did you use Google to look for: "measure dc current arduino"?
Yes although I didn't know what component would be the most appropriate and wanted some advice before buying.
I had a look at some components but wasn't sure what work work with upto 50A
Thanks
Did none give a range of amperage?
Hello thj3648
Take a search engine of your choice and ask the WWW for INA219.
Have a nice day and enjoy coding in C++.
Thanks,
Just had a look at one of these.
It says max current 3.2Amp so not sure it would be capable. Also I am not sure that the wire connectors for the INA219 will be big enough for the cable I am using for the current being drawn by the motor in the circuit.
Thanks
Hello thj3648
If you are not sure you may have to read and study the basic for voltage and current measurement technique.

You need an external shunt resistor for currents that high. The INA219 will work with one.
the current being drawn by the motor in the circuit.
Please provide details of this motor, like a link to the data sheet or product page. For the INA219, it must be a DC motor.
Hi I didn't buy this motor, and can't find much info about it.
I have attached a picture of the sticker on it.
Are there any proper guides on how to connect the INA219 and External shunt resistor that you know of?
Thanks
Adafruit has one. Study the INA219 data sheet very carefully.
The start/stall current of that motor could be as high as 150 A.
Hello thj3648
And take view into the libary, too.
