I want to build an Amp Probe

G McMurry

Has anyone built an AC Amp Probe. I need to measure current 0 - 50 amps of AC. I also want to measure AC volts but I can figure that out. The main issue is that I need a small current coil that I can operate about 3M away from the Stamp. I would like to only use "1 wire".

Something like this? https://www.digikey.com/us/en/techzone/sensors/category/Current.html

Yes -- but that is just the coil... There are sub modules that can measure just about anything from barometric pressure to IR. If I want to measure current, it looks like I need to do some analog design, etc...

I am looking for some sort of 1 wire sub-assembly.

I would like to use RCTime for the measurement.

Does anyone know of a clamp-on or pass through module that converts AC Current to 0-5 DC volts so it can directly be read by RCTIME.

Actually, I read more detail from the Digikey site. There are several current sensors that will do the job. Please ignore the above response. Digikey easily has the answer to my question.

Looks like it would be perfect.
