[ALPHIoT POWER Case Study] Mitachi Industries Co., Ltd.

Real-time and high-precision measurement of snow depth! "ALPHIoT POWER" has been adopted as the power source for the snow monitoring system.

Mitachi Sangyo Co., Ltd. has developed a system to monitor snowfall conditions in snowy areas using sensors. Previously, municipal staff would physically patrol to check the snow accumulation when deciding whether to dispatch snowplows, but with the introduction of the new system, snowfall can now be monitored automatically. It has already been trialed in over 10 municipalities, primarily in the Tohoku and Hokuriku regions, with some having officially adopted it. Dedicated devices equipped with sensors are installed on poles, such as streetlights, at a height of about 3 to 5 meters above the ground to measure the snow depth on the road. The data is displayed on computer or smartphone screens, allowing for real-time monitoring, and notifications are sent via email or phone when the measurements exceed pre-set values. The dedicated devices have been upgraded to a multi-point version equipped with multiple sensors, improving measurement accuracy and enhancing waterproof performance. Our product "ALPHIoT POWER" is also IP66 compliant, which was a key factor in its adoption. There is no concern about solar panels losing power due to snow accumulation, allowing for long-term operation without the need for removal after a single installation.
