Digital Wattmeter With Voltage And Current Display

I have tried to give you all the information you need to design digital watt meter using pic microcontroller.

Digital wattmeter with voltage and current display.

Digital dc watt meter main components. Cheap current meters buy quality tools directly from china suppliers dc 0 100v 10a lcd display digital voltmeter ammeter wattmeter voltage current power meter volt detector tester 12v 24v 36v 1000w enjoy free shipping worldwide. Because microcontroller does not understand current. Liquid crystal display is used to display voltage current power factor and real power value.

The average over at least one cycle is the real power. The real power divided by the apparent volt amperes va is the power factor. Liquid crystal display is used to show measured value of dc power. But if you want to hire us to write code for digital watt meter contact us.

After performing few calculations it then displays the values of voltage current and power on the lcd display. Limited time sale easy return. Measuring the voltage and current will always be helpful while making or debugging any electrical system. 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.

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. Beside that the wattmeter measures also the mean rms standard deviation maximum minimum and frequency of both the voltage and current. For each sample the voltage is multiplied by the current at the same instant. Depending on the used display two or four parameter can be read simultaneous.

Our ac voltage display designed with a switch for clear electric energy and come with a 15 5mm ct with fast measuring speed of 2 times s. A modern digital wattmeter samples the voltage and current thousands of times a second. I recommend you to write your own code for digital watt meter. Microcontroller can read voltage directly.

And it can measure the area of the voltage flux and current charge and keeps track of the measure time. The watt meter panel adopts clear lcd displaying accurate voltage ampere active power and electric quantity measuring values.
