Abstract:
[Purpose/Significance] Agricultural sensors are the foundational technology for modern agricultural development models such as digital agriculture, information agriculture, and smart agriculture. They are also a significant driving force for the iterative upgrade of agricultural technology and the transformation of agricultural production methods. The application environment of agricultural sensors (water, air, and soil) and monitoring targets (plants and animals) is diverse and complex, and therefore, agricultural sensors with high environmental adaptability, high reliability, and low cost are fundamental and core to achieving smart agriculture.
[Progress] This paper classifies agricultural sensors and analyzes the cutting-edge research trends in agricultural sensors, reviewing the research status of agricultural sensors in different application scenarios. It provides an in-depth analysis of four major categories: agricultural environmental sensors (water, atmosphere, and soil), life information sensors for plants and animals, agricultural product quality safety sensors, and agricultural machinery sensors, summarizing the generalities and limitations of existing agricultural sensors in the research and application process.
[Conclusion/Perspectives] In the challenges and perspectives faced by agricultural sensors, the core bottlenecks of the current insufficient large-scale application of agricultural sensors are analyzed, including low cost, specialization, high stability, and adaptability. The concept of “ubiquitous perception in agriculture” is summarized to provide ideas and references for the technological development of agricultural sensors.
