Iot based energy meter reading using arduino microcontroller.

Arduino energy meter circuit.

According to this voltage and current arduino does the maths for calculating power and energy. This smart energy meter using iot does automatic energy monitoring and billing. Please help me out in this regard im using elmeasure energy meter of model lg1129 bm5140 rs485 to ttl converter module link. Current sensing is done by measuring the voltage drop across a current sense 0 005 ohm resistor that s wired into the mains.

Circuit diagram for iot based energy meter using arduino and nodemcu is given above connect esp12 as below. Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started. How to build an arduino energy monitor measuring mains voltage and current. 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. Once i get the hardware fully sorted and release the designs then i ll include the code too. The heart of the energy meter is an arduino pro micro board. Energy meter circuit fig.

The code isn t that useful without the hardware anyway. The arduino senses the current and voltage by using the ina219 current sensor and temperature is sensed by temperature sensor ds18b20. The code is shown in the attached images here is the link to download the energy meter code. Our open hardware energy monitoring arduino compatible shield featuring the above circuit alongside voltage measurement for real power calculation.

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. 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. Project for final year engineering students download abstract ppt a block diagram etc. Connect tx of esp12 rx of arduino.

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. Connect rx of esp12 tx of arduino.
