Im creating a battery,and I want to measure the current and voltage?Which possible circuits could help me? To clarify my question,I doing a DIY battery and afer that I want to measure the results.So I want to measure the current and voltage. Would it be better INA219 or current and voltage sensor connected with ADC?

Thank you!

  • Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking.

    As your question is asked you cannot. You need external sensors such as a A/D which will also work with some current sensors. You can do this with SPI or I2C as examples. At this point you need to put together some sort of specification stating voltages, current, batteries to be measured and power supply capacity if it is portable. Google voltage meter and current or VOM, you can get lots of examples in the arduino forum as well.

  • I think your question may be answered here. You will of course need additional hardware as the RPi has no analog inputs.

  • @Gil,I understand that this is not possible using Raspberry pi,I wanted to ask which possible circuits can I use for that.After I searched I found some Current and Voltage sensor,combined with ADC can be used to measure voltage and current,and then with a python script the values come.Would you recommand this way or INA291?Thank you!

  • @Seamus,I dont want to measure the current power consumption of Raspberry Pi,but Im creating a DIY battery and I wanted to see the results,so voltage and current.Which external circuit would you recommend?INA219,current sensor,voltage sensor? Dec 21 '21 at 16:25
