Web Project: IOT Energy Monitoring

IOT Energy Meter adalah projek yang memantau penggunaan tenaga elektrik dalam unit kWh. Selain bacaan tenaga elektrik, terdapat beberapa bacaan lain iaitu voltan, arus, kuasa (power), power factor (pf) dan frekuensi. Bacaan di simpan di dalam MySQL.

Projek ini menggunakan Eastron SDM230 Smart Meter. Meter ini menggunakan interface RS485. Data protocol nya menggunakan Modbus dan nilai bacaan nya di dalam format 32bit IEEE 754. Bacaan IOT Energy Meter boleh dilihat di http://shahrulnizam.com/iot/energy.php. Selain daripada menggunakan NodeMCU, projek ini juga boleh menggunakan Raspberry Pi IOT Energy Monitoring.

Skematiknya adalah seperti berikut.

PCB komponen layout nya adalah seperti berikut.

Harga projek NodeMCU IOT Energy Monitoring adalah RM940 dan ESP32 IOT Energy Monitoring adalah RM960 tidak termasuk bantuan teknikal. Di bawah adalah cara projek ini berfungsi.

  1. sir;
    i am b.tech 3 rd year student and i am kind of struggling with a new idea or aspects in the field of energy consuming and billing through energy meter and internet …that’s iot…
    few ideas i have regarding that like—THEFT PROTECTION AND DISCONNECTION..
    AND
    ESTIMATION THROUGH VOLTMETER SENSORS,CURRENT AND POWER FACTOR,PHASE ANGLE …AND ALSO SOME FOR MAKING AN AMAZING SMART SYSTEM. (energy flow…)
    your project was amazingly well..i’m deeply inspired..i am wondering to get help to make that iot server too..so please do send me your help to my email-id..it will be my pleasure…

    so please help me with something which could be implemented into this.. and also send me schematics of this project.
