Diy real energy meter with arduino and esp8266.
Arduino energy meter pdf.
The pin number d8 of arduino is attached to the switching side of an optocoupler for detecting pulses coming from energy meter.
It hampers the life of every one.
Recharging should be carried out on the meter.
When a pulse occurs from energy meter optocoupler is.
We cannot directly connect energy meter s led with arduino because led possesses analogue signals while we are feeding arduino on the digital side.
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.
You can also study an article on how to design a 3 phase smart energy meter using arduino here.
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.
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 heart of the energy meter is an arduino pro micro board.
Prepaid energy meter has been implemented in several countries.
Arduino based wireless power meter author.
Due to this problem i designed a solar syste.
The code is shown in the attached images here is the link to download the energy meter code.
One avenue through which today s energy problems can be addressed is through the reduction of energy usage in households.
During my childhood days continuing studies after dusk was a real challenge.
The arduino senses the current and voltage by using the ina219 current sensor and temperature is sensed by temperature sensor ds18b20.
The existing utility system only provides feedback at the end of the month in the form of a bill and consumed kilowatt hours kwh.
The whole schematic is divided into 4 groups.
Since this meter only.
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.
The problem arises when the consumers leave and the electric.
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.
Play video i belong to a village of odisha india where frequent power cut is very common.
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.
