The Low Cost IOT Based Smart Monitoring System is a multi-functional security and environmental monitoring platform. Developed using the ESP32-CAM, the system provides a robust yet affordable alternative to traditional surveillance. It is specifically designed to detect motion, capture visual evidence, and monitor environmental stability in home or industrial settings.
The system utilizes a Passive Infrared (PIR) sensor and a vibration sensor to monitor activity. When an intrusion is detected, the ESP32-CAM module is activated to capture a photograph of the subject. These images are transmitted securely over Wi-Fi to a designated Telegram Bot, providing the user with real-time visual alerts on their smartphone.
Simultaneously, the DHT11 sensor tracks temperature and humidity levels. This environmental data is uploaded to the ThingSpeak cloud platform, allowing for historical data analysis and remote climate monitoring from anywhere in the world.
- Intrusion Detection: Motion-triggered image capture with instant notifications.
- Cloud Analytics: Real-time environmental tracking (Temp/Humidity) via ThingSpeak.
- Remote Control: Integration of a relay module for demand-based control of external devices (e.g., lighting), improving energy efficiency.
- Affordability: Built using cost-effective COTS (Commercial Off-The-Shelf) components.
- Connectivity: Seamless integration with the Telegram messaging API.
Testing under laboratory conditions confirmed the system's reliability:
- PIR Response Time: Approximately 12 seconds for motion detection.
- Notification Speed: Average of 5 seconds for the image to reach the user's Telegram account.
- Environmental Accuracy: Accuracy within ±1°C for temperature and ±2 for humidity.
