Autonomous cyber-physical system for methane gas monitoring in rice fields

Overview

The agricultural sector, particularly rice cultivation, is a significant source of methane emissions—a potent greenhouse gas contributing to climate change. This autonomous cyber-physical system addresses the challenge of monitoring methane concentrations in rice fields and wetlands, which are among the largest contributors to agricultural methane emissions. Designed for deployment in remote locations, the system offers a reliable, continuous environmental monitoring solution that supports climate change mitigation and sustainable agriculture practices.

Technical specifications

The system integrates multiple hardware and software components into a unified monitoring platform:

• Sensor module for detecting methane gas concentrations in the surrounding environment
• Processing module to manage data collection and system operations
• Solar power system enabling autonomous, off-grid operation in remote field locations
• Geo-location module for tracking deployment positions across field sites
• Internet/data communication module for transmitting monitoring data to remote servers
• Monitoring application for visualizing and analyzing collected emissions data

Future development plans include expanding sensor compatibility to support multiple gas types and developing a mobile application capable of monitoring multiple field stations simultaneously.

Technology readiness level

The prototype has been developed and validated through field testing, with results published in a peer-reviewed conference proceeding. The system has demonstrated functional capability for autonomous methane monitoring in rice field and wetland environments. Further validation work is planned to assess long-term device durability over extended testing periods of several weeks to months, and to refine the prototype design for broader sensor integration and multi-station monitoring capabilities.
