The 'Moisture Power Holder' is a plant weight monitoring type irrigation control controller that realizes 'liquid supply control according to moisture stress,' considered a 'master's technique.' Using a load cell, it continuously measures the weight of representative plants (plant + growing medium) and, based on the maximum plant weight after irrigation in the early morning as a reference value, it starts irrigation when the relative value falls below a set threshold. The appropriate irrigation amount for each irrigation is also automatically determined based on weight measurements. It can be applied not only to high-sugar tomatoes but also to other vegetables (regular tomatoes, strawberries, etc.) and ornamental plants (gerberas, etc.). 【Implementation Effects】 ■ Stabilization of drainage rate (drainage amount/irrigation amount × 100) is possible. ■ In the cultivation of mini tomatoes, an average sugar content of 9 degrees and an average fruit weight of over 15 kg were achieved with 7-tier pinching cultivation, with functional components (GABA) increasing to more than three times the usual level. ■ By setting irrigation conditions such as thresholds according to production goals, irrigation management can be entrusted throughout the cultivation period. *For more details, please download the PDF or feel free to contact us.

The "Data Logger System" is a system that allows for the monitoring of multiple devices installed at water supply facilities via a computer. It communicates with each measuring instrument in real-time, managing the monitoring of operational status as well as daily, monthly, and annual reports. For communication, a VPN network is employed. A continuously connected server monitors the status of the water supply equipment and will notify various parties via email in the event of any abnormalities. This system can be confidently implemented as it allows for the confirmation of abnormalities and recovery even during holidays and nighttime hours when it is difficult for water supply management personnel to cover. 【Features】 ■ Safety 　・The use of a VPN (Virtual Private Network) for communication prevents unauthorized access and data tampering from external sources. 　・Each location operates in a standalone manner (i.e., each location functions independently), so even if communication is interrupted due to an accident, the operation of the measuring instruments will not stop. *For more details, please refer to the PDF document or feel free to contact us.
