Circuit Diagram Of Energy Meter
Circuit diagram for iot based energy meter using arduino and nodemcu is given above connect esp12 as below.
Circuit diagram of energy meter. Presented here is a simple energy meter using analog device s ade7757 chip for single phase 2 wire phase and neutral systems used in households. The code is shown in the attached images here is the link to download the energy meter code. Below are the the connections diagrams for installation of a single phase 3 phase 4 wire kwh meter digital or analog energy meter from the supply to the main distribution board in home.
The meter is less expensive and accurate. I am elctrical student plz upload ups with battry conacation and solar plates conaction cantroler with battry and kindly upload 3phase house waring. 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.
Its salient features are. 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. Connect rx of esp12 tx of arduino.
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. Energy meter or watt hour meter is an electrical instrument that measures the amount of electrical energy used by the consumers. These graphics below shows the above idea in a very simple way.
The energy is the total power consumed and utilised by the load at a particular interval of time it is used in domestic and industrial ac circuit for measuring the power consumption. Our integrated circuits and reference designs help you create smarter electricity meters with advanced security and connectivity features to meet system design requirements. Can read up to 999999 units kwh with a resolution of 0 01 units 2.
Energy meter circuit fig. Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started. The red wire shows the live or line or phase and the blake shows the neutral wire.
