Build a Smart Power Strip Indicator with Arduino Uno and ACS712 Current Sensors

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

When you plug multiple appliances into a power strip, you often wonder which ones are actually drawing power. With this kit, you’ll assemble a panel of LED indicators that light up only when current flows through each socket, turning a simple power strip into a smart monitoring tool. It’s a perfect hands-on project for young makers exploring home automation and current sensing.

What You'll Build

You’ll wire four ACS712 current sensor modules to an Arduino Uno, each monitoring a socket. When current above a preset threshold flows through a socket, the corresponding LED glows — giving you a real-time visual snapshot of power usage across your power strip.

What You'll Learn

• How to interface ACS712 current sensors with an Arduino Uno
• Reading analog voltage and converting it to current values
• Programming LED indicators to respond to real-time sensor data
• Applying basic threshold logic for appliance detection
