ESP32 Motion Sensor Security Kit - Predict Heating, Record Occupancy
ESP32 Predictive Home Security Kit - Motion Sensor, Occupancy Logger & Heating Control
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 an ESP32 into a self-learning security and energy management hub. This kit records motion events from two PIR sensors, logs temperature and humidity from two DHT22 probes onto a microSD card, then uses that week of data to predict when rooms are occupied - and switches a 4-channel relay to pre-heat your home before you arrive. It's a complete, standalone unit you solder and enclose, no cloud needed.
What You'll Build
You'll assemble a compact board that timestamps every motion trigger and environmental reading with a DS3231 real-time clock, displays live status on a 0.96-inch OLED, and stores logs for 7 days. The ESP32's onboard algorithm then learns your heating schedule from occupancy patterns and drives the relay module to switch a boiler or heater. The result is a predictive security system that fails safe - if motion is detected at an unexpected hour, you can sound an alert or log the anomaly.
What You'll Learn
- Writing ESP32 firmware that records motion events and learns occupancy patterns over a week
- Interfacing multiple sensors (DHT22, PIR, RTC, OLED) and a microSD card over I2C and SPI
- Using a 4-channel relay to control high-voltage appliances like a boiler from logic-level signals
- Designing a stable dual-voltage power supply with the LM2596 buck converter and 100nF decoupling capacitors

Who This Kit Is For
Ideal for B.Tech ECE/EEE students building a capstone or Smart India Hackathon project that demands real-time sensor fusion and predictive control. It also suits advanced hobbyists and ATL Tinkering Labs looking to demonstrate an end-to-end IoT security system with actionable energy savings - a project that stands out in evaluations at IITs, NITs, VIT, and BITS.
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?
The AI companion shows pinouts, wiring, and code step-by-step; you can also send a photo on WhatsApp and we'll help you debug the same day.
Do I need prior experience with ESP32?
Yes, this kit assumes you can set up the Arduino IDE for ESP32 and have compiled basic sketches. The AI guide bridges any gaps with example code.
How does the predictive heating algorithm work?
The ESP32 logs motion timestamps to the SD card for 7 days, then a simple moving-average pattern detects typical occupied hours. The relay activates 20 minutes before expected arrival, adjustable in code.
Can I monitor the system remotely?
Out of the box, the OLED shows live data. To add remote monitoring, you can connect the ESP32 to Wi-Fi and send logs to a web dashboard or Blynk - the AI companion includes optional snippets for this extension.
Home Security - Records occupancy for 7 days. Learns heating schedule and controls boiler relay predictively.
