Good day. I have a question about measuring electric current using Raspi. I have a voltage of about 0-40V in the circuit. It has the shape of a sine. There is a resistance of 100komh - 10Mohm in the circuit. I need Raspi to measure my current. Can you advise me what parts to use for this? And any scheme? (I'm sorry for my english )
- Voltage - approx 40V
- current range - 1uA - 100mA
- Frequency - 1kHz
- It doesnt have to be very accurate. I want it to be mainly cheap.
- components - It doent matter what components I use.
