How measure DC Voltage and Current and build Energy meter with LCD Display

How measure DC Voltage and Current and build Energy meter with LCD Display | Lesson 104

День тому

In this lesson we learn how to use shunt resistor to measure the current using Arduino. then we show you how to display the current on LCD1602. Then we learn how to measure any DC voltage using Arduino and the same time measuring current to calculate the power and energy and display it on LCD or serial monitor.

Hii My question is when you set the analog refrence to internal i.e 1.1v won't it affect the readings of voltage coming from voltage divider?

@AI.AUTOMATION. Місяць тому

Hii sir In my project my dc voltage is 450v dc 40A and i need to measure the current with Arduino it's safe to Arduino to connect control ground and arduino ground?? Please reply love from India 🇮🇳❤

Hello I am in sti2d terminal and I have a project to present which is the smart cane for blind people and in this project I must use an accelerometer which plays the role of the motion detector and I must add the alarm clock/sleep function it that is to say when the cane moves towards an axis it lights up and when it does not move it is off. I need help because I'm really lost

AC current and voltage project with LCD would be really good..there is very little info on the internet other than the Emon stuff

@robojax Рік тому

Here is current sensor for Ac ukposts.info/have/v-deo/o6qJo6uKsayU0Ww.html

@edinfific2576 Рік тому

Isn't there a sort of an averaging function that can be placed in the code, so that your current readings contain less noise and variations?

@robojax Рік тому

I have shown how to take the average. The rest depends on the tolerance of the shunt resistor. Get better shunt resistor.

@jeffvenqueleir2036 Рік тому

nice video but mabe you can give a example in the futur with a ads1015 or a ads1115 for a shunt and voltmeter with a voltdivider

I have got converter and God willing will make the video. Thanks

helpful video😍🤟 hmm just wanted to ask if i wanted to show the (Ah) of the battery instead of energy. what would be the code?

@robojax Рік тому

Hi, I have explained the code fully and if you know how to calculate the capacity of battery with pen , easily you can do it as we have all the information needed to calculate capacity. Just learn the formula and then come back to the video and use the values from the code.

Hey!! Great explanation!!! Can you please write this code for displaying voltage and current in tm1637 display

@robojax Рік тому

Hi, TM 1637 is just junk. Very hard to use with decimal points as I spent hours in many days . Then gave up. I found a display that can display easily any value here is the video ukposts.info/have/v-deo/bJF0m36FgaJqzI0.html just watch and it would be very each to use the energy meter code and display it.

@arhamupadhye5157 Рік тому

Hey!! thanks for the support, but the problem is hk16k33 is not easily available. What if I wanted to display only the current and voltage part from the energy meter in a 16x2 lcd display. Please tell the changes that I would have to make in the code!!

@robojax Рік тому

Hi, the HT16K33 should replace this junk TM1637. I have made so many videos unfortunately for TM1673. I wish I could delete them . I remember when I found the HT16K33 I was like "yes I found it" kind display. I have the link to purchase under the above video and I am also selling it on Amazon. Good luck.

@mohammadmohd2541 Рік тому

I have a question, since the current is suppose to move in the bath witch has the lowest resistance and assuming that that the resistance of the load is higher than the resistance of the voltage measuring circuit, then this would create a problem. The whole current would be moving in the voltage measuring circuit. Do you have an explanation?

@robojax Рік тому

This will not happen. Measuring voltage is separate from current.

@raoufselwaness Рік тому

can i use the same method to measure 10 -15 amps through 0.1 ohm resistor thanks in advance

@robojax Рік тому

Yea you can use it with the shunt . Just calculate the mC value of the resistor and A ratings. Like 20A 30mV

@herrkronen9694 5 місяців тому

Hi ! Does this method work for AC Current? or is neccesary to make constant sampling to get Peak to Peak Current and then pass it to IRMS Current ? Plz

@robojax 5 місяців тому

if you convert it DC and then do what you said, it should work.

Can it be used with an op amp to read current less 10 amps?

@robojax Рік тому

No. Hyde smaller shunt for any current you want . I thought there won’t any questions as I explained the tolerance of 6.5% for 100A shunt . Please b watch carefully

Dear robojax How can i used this code for arduino dc energy meter for battery high voltage and low voltage protection pls help me

@robojax Рік тому

It can work with virtually any voltage. For protection, it has already action and I have show how to take action. You just need use a relay to connect or disconnect something when your protection condition is met.

I spent over a week to write code and library and test the project to make it work Z I just checked it and in 363 days it was been watched about 12000 time and brought me $29. Now if we calculate hourly earnings it is $0.58/hour . My knowledge and experience worth $100/h and this UKposts is not appreciating knowledge. Only prank and junk is earning. Not worth working on it. I am sorry for myself.
