Home Security & Sleep Mode Automation Kit with Arduino Uno, LDR and RTC

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

Imagine walking into your bedroom at night and the room knows it’s bedtime. The lights gently dim, the thermostat adjusts to a comfortable sleep temperature, and the security motion sensor arms itself — all without touching a switch. This kit lets you build exactly that, blending light detection, real-time clock logic, and PIR motion sensing into a single intelligent system.

What You'll Build

You’ll assemble and program a smart bedroom controller that reads ambient light via LDRs, tracks time with a DS3231 RTC module, and uses a HC-SR501 PIR sensor to trigger security alerts. The system automatically dims lights through a relay when darkness coincides with your set bedtime, and switches a thermostat (or fan/heater) to sleep mode. An OLED display shows the current state and security status at a glance.

What You'll Learn

• Programming time-based automation logic with an RTC module
• Interfacing analog light sensors (LDRs) and calibrating thresholds
• Controlling AC appliances safely using a 4-channel relay module
• Fusing multiple sensor inputs (light, time, motion) for smart decision-making

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for CBSE Class 11-12 students building electronics projects, B.Tech ECE/EEE first-year students, and ATL Tinkering Lab members exploring smart home automation. It is also a hands-on project for Smart India Hackathon participants or hobbyists at VIT, BITS, and NIT campuses wanting to prototype real-world IoT security logic with live sensor feedback.

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.
