A former Center for Astrobiology researcher’s research topic on photosynthesis has progressed into a new technology for smart agriculture!
This is the result of research that the lead author of the paper, Dr. Kozuma, was still conducting when he was at ABC!
小型センサで植物を見守るスマート農業の新技術を開発
〜クラウド連携でいつでも、どこでも健康状態のモニタリングが可能に〜
Key Points：
- We have developed a compact sensor that is attached to the underside of plant leaves to detect changes in leaf color, chlorophyll (Note 1) content, and stress response.
- The developed sensor is water-resistant and battery-powered for long-term continuous measurement, and the measurement data can be viewed anytime and anywhere via the cloud.
- The relatively low cost of the sensor makes it possible to monitor plant health over a wide area or at high densities by installing many sensors.
Abstract：
Due to the effects of climate change and population growth, agriculture faces an urgent need for efficient resource management and increased productivity. Against this backdrop, smart agriculture is attracting attention, especially for technologies that can remotely monitor plant conditions.
Associate Professor Koichiro Miyamoto of the Graduate School of Engineering at Tohoku University and Assistant Professor Kaori Agatsuma of the Graduate School of Life Sciences (currently Graduate School of Agricultural Science, Kyoto University) have devised and developed a new compact sensor that can remotely monitor plant health using a smartphone or other terminal. The sensor can be attached to the underside of a plant leaf to accurately measure the physiological response of the leaf without blocking sunlight. The measured data is shared via online storage and can be monitored remotely and in real time. It can also detect leaf color, chlorophyll content, and environmental stress, paving the way for long-term continuous and multi-point simultaneous measurement systems. This compact sensor can be fabricated for only a few thousand yen and is expected to be used in the agricultural and other fields.
