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.
Arduino energy meter circuit.
Our open hardware energy monitoring arduino compatible shield featuring the above circuit alongside voltage measurement for real power calculation.
When 100a flow through primary 1 turn wire the secondary coil will have 50ma.
It gets isolated from the arduino board and amplified to the range of the arduino s reference voltage.
Please help me out in this regard im using elmeasure energy meter of model lg1129 bm5140 rs485 to ttl converter module link.
The heart of the energy meter is an arduino pro micro board.
According to this voltage and current arduino does the maths for calculating power and energy.
Once i get the hardware fully sorted and release the designs then i ll include the code too.
Project for final year engineering students download abstract ppt a block diagram etc.
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.
This smart energy meter using iot does automatic energy monitoring and billing.
Circuit diagram for iot based energy meter using arduino and nodemcu is given above connect esp12 as below.
The whole schematic is divided into 4 groups.
The code isn t that useful without the hardware anyway.
Iot based energy meter reading using arduino microcontroller.
Connect rx of esp12 tx of arduino.
The arduino senses the current and voltage by using the ina219 current sensor and temperature is sensed by temperature sensor ds18b20.
As any other transformer sns current ct013 100a has primary and secondary windings the ratio is 100 0 05 i e.
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.
Energy meter circuit fig.
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.
Current sensing is done by measuring the voltage drop across a current sense 0 005 ohm resistor that s wired into the mains.
On the other end the sensor have 3 5 mm audio jack where you can plug in mating connector and connect to arduino.
