Home Security Motion Sensor Kit
Build Your Own ESP32-CAM Home Security System with Motion-Activated Telegram Alerts
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 a simple PIR sensor and ESP32-CAM into a fully functional surveillance node that sends high-resolution snapshots straight to your Telegram whenever movement is detected, and stream a live view from any browser—all built, soldered, and configured by you. This project delivers a reliable, customisable home security system that doesn't depend on cloud subscriptions or third-party servers, putting you in complete control.
What You'll Build
You'll assemble a compact monitoring unit inside the provided enclosure, powered by a regulated 5V supply that ensures stable operation for both the camera and the wireless module. Once motion triggers the HC-SR501 PIR, the ESP32-CAM snaps a photo and pushes it instantly via WiFi to your dedicated Telegram bot—giving you immediate mobile notifications. You'll also set up an MJPEG live stream accessible through any browser on your home network, turning the device into a real-time viewing station.
What You'll Learn
- How to regulate power for sensitive camera modules using LM1117 3.3V regulators, electrolytic capacitors for bulk filtering, and ceramic caps for high-frequency decoupling.
- Programming motion-triggered callback logic that integrates with Telegram’s Bot API to push images and text alerts in real time.
- Configuring the ESP32-CAM to serve a live MJPEG stream while simultaneously listening for PIR interrupts and maintaining WiFi connectivity.
- Soldering all through-hole components on a PCB prototype board—mounting the PIR sensor, buzzer, and power circuitry into a secure, self-contained chassis.

Who This Kit Is For
This advanced kit is built for engineering students (B.Tech ECE/EEE) tackling IoT capstone projects, professionals prototyping a custom security solution for a home or small office, and experienced hobbyists who have already completed basic Arduino or soldering projects. It’s equally useful for Smart India Hackathon teams focusing on surveillance and safety, final-year demo prototypes, or faculty setting up a hands-on embedded systems lab.
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 open your AI companion; it has every wiring diagram, code snippet, and troubleshooting step. If you still need a human touch, our WhatsApp support responds within hours.
Do I need to know soldering before buying this kit?
Yes, soldering is required to assemble the power regulation and sensor board. The kit includes a soldering iron and wire, and the companion includes a soldering guide, but we recommend prior basic soldering practice.
Can I view the camera feed from outside my home network?
The live stream works over your local WiFi by default. For remote access, the companion explains methods like Duck DNS with port forwarding or secure tunnels such as ngrok, but you’ll need to handle advanced router settings.
What if my Telegram bot doesn’t receive alerts?
The companion has a dedicated Telegram verification flow—it checks your bot token, chat ID, and WiFi credentials. If the issue persists, just message us on WhatsApp and we’ll help you debug the configuration.
Home Security — ESP32-CAM captures image on PIR trigger and sends to Telegram bot over WiFi. Live stream via browser.
