Smart Bed Occupancy and Sleep Monitor Kit with Arduino Uno + LED
Smart Bed Occupancy and Sleep Monitor Kit with Arduino Uno & OLED Display
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your ordinary bed into a smart sleep lab. Place thin FSR sensors under each corner of your mattress; they detect when you're in bed and how much you move. The Arduino Uno logs occupancy timestamps and a custom-calculated restlessness index onto a microSD card with precise real-time clock timestamps. A movement score derived from rapid pressure fluctuations gives you an objective view of sleep quality.
What You'll Build
You'll assemble a complete bed-occupancy sensing system: four pressure sensors wired in voltage-divider configuration, read by the Arduino and displayed on an OLED screen. Data is saved to a microSD card with date and time from the DS3231 RTC module, creating a CSV log you can open in any spreadsheet. The system runs on a 9V battery, making overnight monitoring completely cable-free. You'll be able to analyze sleep patterns, bed exit times, and movement intensity.
What You'll Learn
- Calibrating Force Sensitive Resistors (FSR 402) for weight detection
- Interfacing DS3231 RTC for time-stamped data logging
- Designing analog signal conditioning circuits with resistors and capacitors
- Structuring CSV data on SD card for later analysis

Who This Kit Is For
This kit is designed for engineering students pursuing B.Tech in ECE/EEE or diploma programs, especially those working on home automation or healthcare projects. It's an excellent choice for hackathons like Smart India Hackathon, final-year mini projects, or IIT/NIT/VIT coursework — anywhere a sensor-driven data logging system is required.
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 launch the AI build companion trained on this exact project. It provides step-by-step guidance and debugging help. You can also reach our WhatsApp support for human assistance.
Can I see live bed occupancy on the OLED without an SD card?
Yes, the OLED displays real-time occupancy status and a movement score. The SD card logging is optional but highly recommended for sleep pattern analysis over time.
How accurate are the FSR sensors for measuring restlessness?
FSR 402 sensors detect relative pressure changes — not absolute weight. By placing one under each mattress corner, you can reliably identify sleep onset, exit, and periods of high movement. It's not medical-grade but provides meaningful home-automation and wellness insights.
Is this kit suitable for a college engineering project or Smart India Hackathon?
Absolutely. The kit aligns with university curriculum for embedded systems and IoT. It's been used in B.Tech final-year projects and hackathons, with the added advantage of an AI guide that helps you meet tight deadlines.
FSR pressure sensors under mattress corners detect occupancy and estimate sleep restlessness. Logs to SD with RTC.
