Arduino energy meter pdf.
When a pulse occurs from energy meter optocoupler is.
One avenue through which today s energy problems can be addressed is through the reduction of energy usage in households.
The above articles will give you step by step details towards the designing of smart energy meter here in this article the focus is on how to connect some wi fi module with the above designed smart energy meters.
We cannot directly connect energy meter s led with arduino because led possesses analogue signals while we are feeding arduino on the digital side.
The existing utility system only provides feedback at the end of the month in the form of a bill and consumed kilowatt hours kwh.
You can also study an article on how to design a 3 phase smart energy meter using arduino here.
Since this meter only.
The whole schematic is divided into 4 groups.
It is not a mystery that we usually have doubts about the energy consumption records presented by the bills for this reason i set out to create my own energy meter to be sure of what is really happening if we are being lied to and if we are really.
It hampers the life of every one.
In fact the disadvantage of the system is the behavior control of the users.
The problem arises when the consumers leave and the electric.
This video guide shows you how to build your own energy meter for use around the home using an arudino and a current transformer ct.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
We built our source code to handle up to 5 inputs measuring and 5 out measuring you just need to add more cts and pts for each additional input outputs as we will discuss that in hardware section.
Prepaid energy meter has been implemented in several countries.
Diy real energy meter with arduino and esp8266.
According to this voltage and current arduino does the maths for calculating power and energy.
Because your setup ct resistors and input voltage may be different there is a scaling factor in the sketch which you will need to change before you will get.
The arduino senses the current and voltage by using the ina219 current sensor and temperature is sensed by temperature sensor ds18b20.
You can measure all electrical parameters for utility input and do the same for renewable source like solar or wind turbine at the same time.
The code is shown in the attached images here is the link to download the energy meter code.
The heart of the energy meter is an arduino pro micro board.
The pin number d8 of arduino is attached to the switching side of an optocoupler for detecting pulses coming from energy meter.
Recharging should be carried out on the meter.
