The project “Online Monitoring of Geological CO₂ Storage and Leakage Based on Wireless Sensor Networks” aims to develop an intelligent and reliable system for real-time detection and monitoring of CO₂ concentration in geological storage sites. The system utilizes a CO₂ sensor interfaced with a NodeMCU (ESP8266) microcontroller to continuously sense and record carbon dioxide levels. The data is displayed locally on an LCD module and simultaneously transmitted via Wi-Fi to an online web server for remote monitoring and analysis. A regulated power supply ensures stable operation of all components. This wireless monitoring approach enables early detection of CO₂ leakage, ensuring environmental safety and efficient management of underground carbon storage facilities. The proposed system reduces the need for manual inspection, enhances data accessibility, and contributes to sustainable carbon capture and storage (CCS) practices.  

Objectives:

 To monitor CO₂ levels in geological storage sites in real-time.

 To design a low-cost and energy-efficient monitoring system using IoT technology.

 To provide early detection of potential CO₂ leakage.

 To ensure environmental and human safety by preventing hazardous exposure.

 To enable remote data access and analysis via a web-based interface.

 To minimize manual inspection and enhance automation in CO₂ monitoring.
