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.

The project aims in designing a system which makes operating of electrical appliances in home through Android mobile phone using IOT. The controlling of electrical appliances is done wirelessly through Android smart phone using the Wi-Fi feature present in it. Here in this project the Android smart phone is used as a remote control for operating the electrical appliances through KNE APP.

Wi-Fi (Short for Wireless Fidelity) is a wireless technology that uses radio frequency to transmit data through the air. Wi-Fi has initial speeds of 1mbps to 2mbps. Wi-Fi transmits data in the frequency band of 2.4 GHz. It implements the concept of frequency division multiplexing technology. Range of Wi-Fi technology is 40-300 feet.

The controlling device of the whole system is an NpdeMCU which has an inbuilt Wi-Fi and Relay along with FOUR DEVICES are interfaced to the NodeMCU. The data received from smart phone is fed as input to the NodeMCU. Then the microcontroller acts accordingly on the Relays to switch connected electrical appliances.

The main objectives of the project are:

IoT based wireless controlling of electrical devices using smart phone.

The project provides exposure to following technologies:

Wi-Fi technology.
Learn about KME APP.
