Background Environmental sensing involves measuring and monitoring various aspects of the natural environment, such as air, water, and soil quality, as well as climate, vegetation, and wildlife. This process is essential for understanding environmental conditions and dynamics, identifying and mitigating hazards, and supporting sustainable development and conservation efforts. Traditional methods, however, often face challenges related to cost, coverage, scalability, reliability, and timeliness, necessitating innovative solutions for real-time, comprehensive data.
Technological Integration The article provides an overview of emerging technologies that facilitate automation in environmental sensing, including ESNs, UAVs, robotics, and DL. Automation is defined as the integration of hardware and software elements into modern analytical systems to reduce human intervention and ensure consistency.
The researchers analyze the benefits and limitations of each technology, along with their current and potential applications. For example, UAVs can be used for aerial monitoring of deforestation, while robotic systems can measure water quality in inaccessible areas. The study also addresses challenges such as interoperability, calibration, communication, longevity, security, privacy, and ethics. Additionally, it emphasizes the importance of transfer learning and edge computing in improving the performance and scalability of automated environmental sensing systems.
