The HLW8032 is a high precision energy metering IC that uses a CMOS manufacturing process and is primarily intended for single phase applications. It can measure line voltage and current, and can calculate active power, apparent power and power factor. The device integrates two ∑-Δ ADCs and a high-precision energy metering core.

The Arduino ADC is a ten-bit converter, meaning that the output value will range from 0 to 1023. We will obtain this value by using the analogRead() function. If you know the reference voltage...The arduino will keep track of the ticks and the count can be read throught the USB serial interface of the Arduino. After connecting, issue command 'c' (count) to read the current count or 'd' (delta ... seemed logical at the time) to read the current count and reset the counter. Shell code to check current tick count only: #!/bin/sh

For current measurement I used a Hall Effect current sensor ACS 712 (20 A)...

Arduino - Rotary Potentiometer Arduino's pin A0 to A5 can work as analog input. The analog input pin converts the voltage (between 0v and VCC) into integer values (between 0 and 1023), called ADC value or analog value. The monitor consists of the current sensor (which produces a signal proportional to the mains current) and the sensor electronics that convert the signal into a form the Arduino can use. For a circuit diagram and detailed discussion of sensors and electronics see: CT Sensors - Introduction; CT Sensors - Interfacing with an Arduino Jan 10, 2020 · VDD to Arduino 5V and A to Arduino 5V through 330 ohm resistor. VEE pin is used to control the contrast of the LCD. A (anode) and K (cathode) are the back light LED pins. Arduino capacitance meter code: Hints: Capacitor discharge pin is Arduino analog pin 1 (A1) and it’s connected to the capacitor positive terminal through 220 ohms resistor.
