Digital Wattmeter With Voltage And Current Display

Testing arduino wattmeter circuit after designing the circuit on a perf board and making all the necessary connections i have used the circuit to test a couple of loads like led and a motor.

Digital wattmeter with voltage and current display.

And it can measure the area of the voltage flux and current charge and keeps track of the measure time. Depending on the used display two or four parameter can be read simultaneous. Liquid crystal display is used to show measured value of dc power. Because microcontroller does not understand current.

Digital dc watt meter is very simple to use and basic idea of digital dc watt meter is given in this project. The watt meter panel adopts clear lcd displaying accurate voltage ampere active power and electric quantity measuring values. In this project we are going to make our own digital ammeter using pic16f877a microcontroller and current sensor acs712 5a this project can measure both ac and dc current with a range of 0 30a with an accuracy of 0 3a. After performing few calculations it then displays the values of voltage current and power on the lcd display.

But if you want to hire us to write code for digital watt meter contact us. For each sample the voltage is multiplied by the current at the same instant. Limited time sale easy return. I recommend you to write your own code for digital watt meter.

A computer circuit uses the sampled. Liquid crystal display is used to display voltage current power factor and real power value. I have tried to give you all the information you need to design digital watt meter using pic microcontroller.

Digital dc watt meter main components. The real power divided by the apparent volt amperes va is the power factor. The average over at least one cycle is the real power. Beside that the wattmeter measures also the mean rms standard deviation maximum minimum and frequency of both the voltage and current.

Measuring the voltage and current will always be helpful while making or debugging any electrical system. A modern digital wattmeter samples the voltage and current thousands of times a second.
