Abstract
Home Monitoring Raspberry Pi Node is an open-source Internet of Things (IoT) project. Raspberry Pi & Node.js diy Home Monitoring & Intruder Alert system. The project is designed as a end to end solution for a DIY Home Monitoring & Intruder Alert system. Besides offering a live video stream on any device (web responsive client), it also actively monitors for movement with the help of a PIR sensor. It is built using JavaScript, Raspberry Pi, Node.js. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.
1. Introduction
The project is designed as a end to end solution for a DIY Home Monitoring & Intruder Alert system. Besides offering a live video stream on any device (web responsive client), it also actively monitors for movement with the help of a PIR sensor.
If an Alarm is triggered, you get a SMS notification on your phone and the snapshots taken during the Alarm time span (customizable - default is 1 minute) are uploaded via FTP to your server.
In order to avoid false positives from the PIR motion sensor, extra checks were added - a detection counter & detection interval. The Alarm gets triggered when the sensor detects movement 3 times in 5 seconds (both values configurable in code).
2. Objective
Raspberry Pi & Node.js diy Home Monitoring & Intruder Alert system
This project demonstrates how JavaScript, Raspberry Pi, Node.js can be applied to a real-world Internet of Things (IoT) problem.
4. Technology Stack
- Raspberry Pi - raspbian, brick button & led, Pir sensor
- Node.js - for the main application
- Mjpg_streamer - to generate the video stream
- Shell scripting - for easy application start (interactive & background)
- Htms/Css/Javascript + Bootstrap - the web client
- Raspberry Pi
- I used Model B Revision 2 with Raspbian - any model should be Ok, just be careful with the Gpio configuration pin mappings, they can differ
- Generic USB webcam (compatible with Raspberry Pi & Raspbian)
5. System Requirements
General requirements for this technology stack — check the README for exact versions.
- Node.js (LTS) and npm
- A modern web browser
- VS Code or any code editor
- Git (to clone the repository)
6. Installation & Setup
git clone https://github.com/orosandrei/Home-Monitoring-Raspberry-Pi-Node.git
cd Home-Monitoring-Raspberry-Pi-NodeFull setup instructions are in the project README.
7. Future Enhancements
Suggested extensions you can add to make this your own project.
- Add a mobile dashboard using Blynk or Firebase
- Store readings in a cloud database for history charts
- Add alerts via SMS / Telegram when thresholds are crossed
8. Viva / Review Questions
Common questions examiners ask for projects in this domain.
- Which microcontroller / board and sensors are used and why?
- How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
- Where is the sensor data stored and visualised?
- How is power consumption managed?
- How would you secure the device and its communication?
