Smart Plug with Appliance Identification (NILM Basics)

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

Objective

Identify appliances from their power signature and report their energy use.

What you will build

A smart plug that measures power with high resolution and uses a simple classifier to tell which appliance is plugged in, such as a fan, kettle, TV or laptop charger.

Results you can expect

• Classification accuracy for 6 appliances
• Energy per day per appliance
• Response to a switch-on event
• And false-identification cases

What you will learn

Load signatures, feature extraction and energy analytics.

Tools and notes

ESP32, PZEM-004T or ADE7953, relay, Python (scikit-learn), MQTT. Mains-connected: enclosure, fuse and an isolated test set-up are essential.

Resume points from this project

• Built and tested Smart Plug with Appliance Identification (NILM Basics); objective: identify appliances from their power signature and report their energy use.
• Measured and analysed classification accuracy for 6 appliances and energy per day per appliance; 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.
