Home Security Motion Sensor Kit with ESP32 + Relay
Build a 20-Device Apple Home Security System with ESP32 Matter & Relays
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit transforms a box of components into a home security nerve center: twenty virtual devices, each mapping to a real PIR motion sensor, temperature/humidity monitor, or relay, all exposed through an ESP32 Matter bridge and controllable natively in Apple Home. Skip expensive proprietary hubs—build a Matter-certified ecosystem from scratch and have full control over your automation logic.
What You'll Build
You’ll assemble a fully functional home security system that integrates five DHT22 temperature and humidity sensors, three HC-SR501 PIR motion detectors, and dual 4-channel relay modules. The ESP32 acts as a Matter bridge, making each sensor and relay appear as a distinct Apple Home accessory. Monitor room conditions in real time, detect movement, and trigger lights or alarms—all without subscription fees or third-party cloud dependencies.
What You'll Learn
- Program an ESP32 as a Matter bridge, advertising sensor and relay endpoints compliant with Apple Home specifications.
- Solder and assemble a multi-sensor board using prototype PCBs, 1N4007 diodes, and 100nF capacitors for noise-immune operation.
- Calibrate HC-SR501 PIR sensors to detect human presence and map each detector to a dedicated virtual motion sensor.
- Use 4-channel relay modules to switch high-current devices based on sensor thresholds, creating automated security responses.

Who This Kit Is For
This kit is designed for B.Tech ECE/EEE students building IoT-based home automation capstone projects, teams preparing for Smart India Hackathon, and advanced makers with soldering and embedded C experience. It also suits IIT/NIT/VIT/BITS students exploring Matter protocol interoperability and Apple Home integration at a professional depth.
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 to activate your AI companion for context-aware debugging, or reach us on WhatsApp for direct guidance within 24 hours.
Do I need an Apple Home Hub to use this system?
Yes, an Apple TV (4th gen or later) or HomePod acts as the Matter border router. The ESP32 bridge requires a hub on the same network to expose devices to Apple Home.
Is soldering required?
Yes, this is an advanced kit. You must assemble the sensor and relay boards using the included soldering iron, solder wire, and prototype PCBs. No breadboard is provided.
Does it work with Google Home or Alexa?
This kit is optimized for Apple Home via Matter multi-admin. After completing the Apple Home setup, you can reconfigure the firmware to share devices with Google Home or Amazon Alexa.
Home Security — ESP32 Matter bridge exposes 20 virtual devices to Apple Home. Each device maps to a real sensor or relay.
