Smart Energy Monitor Kit - Build a Classroom Power Logger with Arduino
Smart Energy Monitor Kit - Build a Classroom Power Logger with Arduino
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Ever wondered how much power your classroom fan, light, or projector really consumes? With the ATL Smart Energy Monitor Kit, you'll clamp CT sensors around appliance wires, let an Arduino calculate real-time power, and log the data to an SD card for analysis. It's a hands-on way to turn curiosity about electricity into a working measurement tool, perfect for school energy audits or CBSE science projects.
What You'll Build
You'll assemble a portable energy monitor that reads current from two appliances simultaneously, displays wattage on a 16x2 LCD, and saves timestamped power logs to a MicroSD card. The system can run for hours to capture usage patterns, giving you concrete data to back up your next classroom presentation or science exhibition.
What You'll Learn
- How to safely measure AC current using non-invasive CT sensors
- Calibrating an ADS1115 ADC for precise voltage readings from a CT sensor
- Programming an Arduino to calculate real power (watts) from current and estimated voltage
- Logging sensor data to an SD card with timestamps for later analysis in spreadsheets

Who This Kit Is For
This kit is designed for CBSE Class 9-12 students tackling energy monitoring projects, ATL Tinkering Lab facilitators running STEM workshops, and school science exhibition participants. It's especially suited for Smart India Hackathon junior categories where real-world data logging is key, helping young makers bridge textbook theory and practical measurement.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Our AI build companion provides step-by-step guidance for this exact kit, and you can reach us via WhatsApp for quick help.
Can I monitor more than two appliances?
The kit includes two CT sensors for immediate use, but you can add extra SCT-013 sensors by expanding the circuit on a breadboard (not included).
Does the kit measure actual voltage from the socket?
No, it assumes a constant 230V AC to calculate power. For dynamic voltage measurement, you'd need an AC voltage sensor module, which can be added later.
How do I analyse the logged data for my project?
The SD card stores data as a CSV file that opens directly in Excel or Google Sheets, letting you create charts of energy usage over time for your report.
CT sensors measure current drawn by classroom appliances - Arduino calculates and logs power consumption.
