hello,
Has anyone tried a 0-300 voltmeter to build with arduino but be fully isolated with optocoupler from source to arduino. Does anyone have any schematics?
reminder, the voltage is at a very high frequency, voltage of plasma arc
Thanks
Your topic was MOVED to its current forum category which is more appropriate than the original as it is not an Introductory Tutorial
It is possible to measure 300V with a voltage divider when using multiple resistors for R1 to lower the voltage over a resistor. If you use a battery powered Arduino, and then use wireless or a optical wire to send the data to another Arduino board, then you can get the data into a computer.
Another option is a USB-isolator, but perhaps an arc might jump over the shorter distance.
How many gazillion Herz is it ?
Our mains is 50 Hz and 50.1 Hz is high. The 5G can go up to 54 GHz, that is high. So I'm guessing that your signal is between 50.1 Hz and 54 GHz, but I could be wrong.
