How to build an arduino energy monitor measuring mains voltage and current.
Arduino energy meter circuit.
On the other end the sensor have 3 5 mm audio jack where you can plug in mating connector and connect to arduino.
When 100a flow through primary 1 turn wire the secondary coil will have 50ma.
Energy meter circuit fig.
There is one analog pin available in nodemcu esp12 we could use that pin but esp series can take upto 3 3 volts on their pins.
The code isn t that useful without the hardware anyway.
Circuit diagram for iot based energy meter using arduino and nodemcu is given above connect esp12 as below.
As any other transformer sns current ct013 100a has primary and secondary windings the ratio is 100 0 05 i e.
1 shows the circuit diagram of the energy meter which is built around energy metering ic with integrated oscillator ade7757 ic1 microcontroller at89c52 ic2 eeprom at24c02 ic3 5v voltage regulator 7805 ic5 opto coupler mct2e ic4 and an lcd display.
The arduino senses the current and voltage by using the ina219 current sensor and temperature is sensed by temperature sensor ds18b20.
Connect tx of esp12 rx of arduino.
Hello all im trying to read holding register data values of energy meter through arduino mega using rs485 to ttl converter from past 1 month but i havent suceeded.
Iot based energy meter reading using arduino microcontroller.
Please help me out in this regard im using elmeasure energy meter of model lg1129 bm5140 rs485 to ttl converter module link.
According to this voltage and current arduino does the maths for calculating power and energy.
Current sensing is done by measuring the voltage drop across a current sense 0 005 ohm resistor that s wired into the mains.
The heart of the energy meter is an arduino pro micro board.
Once i get the hardware fully sorted and release the designs then i ll include the code too.
This smart energy meter using iot does automatic energy monitoring and billing.
It gets isolated from the arduino board and amplified to the range of the arduino s reference voltage.
The whole schematic is divided into 4 groups.
Project for final year engineering students download abstract ppt a block diagram etc.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
Our open hardware energy monitoring arduino compatible shield featuring the above circuit alongside voltage measurement for real power calculation.
