IoT Smart Energy Meter with Real-Time Dashboard

Approx. component budget: Rs. 4,000 - 8,000

Objective

Measure and log the energy use of different household loads and show it live on a phone, with a cost estimate and a limit alert.

What you will build

An ESP32 with a PZEM-004T or similar energy module, a display, a relay and a cloud or local web dashboard showing voltage, current, power, power factor and units consumed.

Results you can expect

• Power and energy per appliance
• Daily and monthly usage graphs
• Power factor of loads
• Cost per day
• Comparison with a normal meter

What you will learn

Energy measurement, IoT communication, data visualisation and how smart meters work.

Tools and notes

ESP32, PZEM module, a free dashboard service or simple web page, Excel. Connects to mains, so use an enclosed box, a fuse and a qualified person for wiring.

Resume points from this project

• Built and tested IoT Smart Energy Meter with Real-Time Dashboard; objective: measure and log the energy use of different household loads and show it live on a phone, with a cost estimate and a limit alert.
• Measured and analysed power and energy per appliance and daily and monthly usage graphs; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
