Measuring static charges with arduino UNO

I was tasked with ''create a simple electrostatic voltmeter using a high resistance voltage sensor''. I have some components i can use. When I asked ChatGPT, it advised me to use something called an OP-AMP. I, hower don't have any knowledge in electronics or programming, so I would like to know:

  1. Is this project even possible, since I tried to read a little about measuring static charges from this forum, and didn't get any good results.
  2. Do I need any other components to make this project work.

That is you first task, gain some knowledge.
This is a good website for learning about electronics

Maybe you could tell us what they are. And perhaps why someone with no knowledge in the field should be tasked to do this?

Sorry for being unclear.
I have to do this project for my physics class. Everyone in our class got a unique assignement, most of which were AI generated.
I have completed a few arduino projects before, and i know the basics, but wouldn't say that I'm in any way skilled. We have all sorts of sensors and such, but i don't know what to look for.

Still unclear! How much study has been done relating to static electricity? Do you understand that a measurement cannot be done directly or the charge will be depleted. It must be measured by comparison to a known voltage and that is where the op-amp comes into the picture.

Have you looked at commercial static charge detectors and how they work?

Also unclear if the assignment actually includes any requirement to not deplete or alter the charge being measured...

I would suggest you do some research and do an internet search. One of the first pages I came across looked most helpful:-

Note this does not mean you use pictures to measure the static charge :wink:

If I wave a Hall Sensor in a static electrical field, the sensor would experience magnetic force.

If I put a small metal plate in an electric field, I might use capactive sensing methods to measure strength at some distance then wrap the plate in a ball of insulation radius 'that distance'. Touch the object with insulation ball, measure with metal plate and circuitry.

Some charge will get moved around, some lost. Get used to it.

If you use the Homemade Electroscope in that last link you can use a camera to detect and measure the deflection. While aluminum might work, using gold leaf is much more sensitive. You can get gold leaf pages in many high end art supply shops.

Seems like this might not meet the requirement of "using a high resistance voltage sensor'' to do the measurement.

Here is a commercial static charge measuring device. Full cast metal case. Screened charge sensor. Turn the device on and use the pot to center the meter. Read the static charge voltage. Never had static problems, so never had a reason to use it. Powered by two 9 volt batteries providing + and - for the op-amp.
