I would like to know if someone has experience with measuring high voltages using an Arduino.
I know you can use resistors to lower the voltage, however.
I want to be able to measure the pulses of an electric fence used to prevent farm animals from escaping. These pulses are high-voltage and will not always be a similar voltage. I want to read these voltages, to scan for differences.
So, I wondered if someone has done something like that, and if the Arduino gets weird when it gets a voltage above 5 V at a low amperage on its analog port.
--here some possible solutions for those wanting to know the answer-- -mostly based on comments and answers below-
- Using resistors as a voltage divider while keeping an eye on the maximum spark gap distance and capacitive coupling.
- using a transformer/coils to reduce the voltage.
- using a high voltage probe to measure it.
- using neon bulbs or other light sources to measure it.
- charging a capacitor and measuring discharge time with high resistance(only works for the total power)
-this list is meant as a summary of what is discussed further ideas and solutions are still welcome-
