Home Energy Monitor Kit

This kit serves one of our pillars: Energy — technology in the service of nature.

See the invisible: how much electricity your gadgets actually use. A current sensor reads the power a low-voltage device draws, the ESP32 shows the watts live and logs them, and you hunt down what wastes energy. (Works on safe low-voltage DC circuits — never mains wiring.)

What's inside the kit?

• ESP-32S 30Pin Dev Board WiFi Bluetooth CP2102 — WiFi brain that logs power use
• ACS712 5A Current Sensor — Measures electrical current
• 0.96" OLED LCD Module — Shows the watts live
• BB-01 Breadboard 830 Tie Point — Build base
• BB-J140 Connecting Jumper Wires for Breadboard (140 Wire) — Connections

How the idea works

Every part in the kit has a job. Assembled in the right order they stop being loose parts and become a working system — one you build yourself, understand at every step, and see the result of with your own eyes. The included build guide walks you from zero to running.

Your journey: from kit to competition

• Build — assemble the kit and get it running.
• Understand — learn why each part is there and how it works.
• Improve — modify it, add a sensor, tune it, try your own idea.
• Make a project — turn the experiment into a project that solves a real environmental problem.
• Compete — enter your project into local and international competitions.

A good fit for tracks such as:

• Energy / الطاقة

What you'll learn

• How a current sensor measures electrical power
• Calculating watts from current and voltage
• Logging energy use over time to find waste
• Electrical safety — why we only measure low-voltage DC

Extend & innovate

Monitor a solar panel's output, compare appliances side by side, and build a dashboard that shows your daily energy use. Turn it into an energy-saving project for your home or school.
