Demand Response Load Scheduler Kit with Arduino Uno + Relay
Save Electricity: Arduino Uno Demand Response Load Scheduler Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Electricity tariffs often punish peak-hour usage, but manually switching heavy loads is impractical. This kit lets you build a smart controller that reads real-time power consumption via PZEM-004T and schedules your appliance to run when rates are lowest — entirely automatically.
What You'll Build
You'll assemble a fully functional demand response controller that toggles up to four heavy appliances based on your configured off-peak schedule. The OLED shows live voltage, current, power, and energy consumed, while the DS3231 RTC ensures accurate timing even during power cuts.
What You'll Learn
- Interface the PZEM-004T energy monitoring module for real-time AC load measurement
- Implement scheduling logic using DS3231 real-time clock and Arduino programming
- Safely switch high-power appliances with relay module and snubber circuit design
- Embed an OLED display for on-device data visualization and system status feedback

Who This Kit Is For
Perfect for CBSE Class 11-12 students exploring electricity tariffs and automation, B.Tech ECE/EEE undergraduates building Smart India Hackathon energy-domain prototypes, and ATL Tinkering Lab mentors looking for a ready-to-go industrial-grade project. The DIN rail enclosure and real-world energy monitoring make it equally suitable for IIT/NIT/VIT/BITS engineering final-year demonstrations.
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?
Scan the QR code on the box to access your AI companion trained on this kit; it provides step-by-step debugging. You can also reach us on WhatsApp for human assistance.
Can I schedule multiple appliances with this kit?
Yes, the 4-channel relay module allows you to control up to four appliances independently, each with its own off-peak schedule programmed in the Arduino sketch.
Is this kit safe to use with home appliances?
Absolutely. The DIN rail enclosure, snubber diodes, and relay module are designed for safe switching of high-power loads up to 250VAC/10A. Always follow the build guide for correct wiring.
Will this work for three-phase meters or only single-phase?
The PZEM-004T module works with single-phase 230VAC systems, which covers most Indian homes. For three-phase, you'd need additional modules, but this kit focuses on single-phase demand response learning.
PZEM-004T monitors grid load. Schedules high-power relay appliances to off-peak windows automatically.
