This project is a great example. [Scott Daniels] takes a look at the other voltage measurement options available to AVR chips used by Arduino.

A device that can be used to measure Alternating Current (AC) voltage level generated from a triboelectric device by rectifying the current to a Direct Current (DC) and read the voltage level through ...

ESP32 with ZMPT101B Repository This repository contains code and resources for interfacing an ESP32 microcontroller with the ZMPT101B AC voltage sensor. Whether you are working on a project that ...

A general method for measuring AC high voltages is to use a voltage divider, with two resistors in series. The resistors are selected so across one of the elements is some arbitrary fraction (like ...

Makerfabs has recently introduced Matouch 1.28-inch ToolSet_AC Dimmer an open-source ESP32-based AC voltage controller for dimming lights or adjusting motor speeds using phase-cut dimming. Built ...

Abstract: Oscillating Wave Test System - OWTS using damped AC Voltages (DAC) is an alternative test method for continuous AC voltage testing for partial discharge measurement of power cables at field.
