This project presents a comprehensive and scalable framework for intelligent real-time monitoring and automation using a smart sensor-based system integrated with a Telegram Bot and blockchain technology. The proposed design ensures secure data acquisition, tamper-proof event logging, and automated emergency responses. Using an ESP32 microcontroller interfaced with multiple sensors—including GPS, BMP280, MPU6050, and gas sensors—the system continuously collects environmental, positional, and safety parameters. The data is transmitted to users via Telegram Bot for instant alerts and control commands, while blockchain technology provides immutable storage and transparent traceability of critical events. Smart contracts automate system responses such as activating cooling systems during temperature surges, triggering ventilation in case of gas leaks, or sending SOS alerts when abnormal orientation is detected. This unified model enhances reliability, reduces operational latency, and prevents data tampering through decentralized control. By combining IoT sensing, real-time communication, and blockchain-based automation, the system establishes a robust foundation for industrial safety, home automation, and environmental monitoring. The design ensures security, transparency, and user accessibility—transforming conventional monitoring into an intelligent, trust-driven ecosystem.
