Cloud management of water level information combined with weather forecasts without the need for a power supply.

The battery-operated water level gauge is an option for the "Disaster Prevention System ZEROSAI" with NETIS registration number QS-150021-VE. It eliminates the need for the conventional 100V power supply and solar power systems, achieving significant cost reductions. It can be easily installed anywhere with 4G connectivity. Information can be centrally managed in the cloud along with various weather data. In the event of a typhoon or sudden heavy rain, it allows for easy relocation or removal to prevent flooding when river water levels are expected to rise rapidly. **Features** - Continuous monitoring of water levels 24/7, with cloud access to water levels every 10 minutes at the shortest. - Can be installed in locations without power supply. - Can be centrally managed in conjunction with weather forecasting and rainfall observation from "ZEROSAI" and "Compass PLUS," as well as danger notifications via electronic display boards. - Can send alerts in conjunction with business chat applications when threshold values are exceeded, including LINE WORKS direct, WowTalk, and Microsoft Teams. *For more details, please refer to the PDF document or feel free to contact us.*

In facilities operating nurse call systems, we have made bed exit sensors wireless, allowing them to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ Bed exit sensors notify wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

On February 24 (Tuesday), the Japan Meteorological Agency announced its three-month forecast for March to May. In the vicinity of Japan, the upper-level westerlies are expected to flow more to the north than usual, making it likely to be covered by warm air. As a result, above-average temperatures are predicted for March and April in regions excluding Okinawa and Amami, and nationwide in May. With an increase in warm days, there may also be days when it feels hot enough to sweat during the daytime. On sunny days, ultraviolet rays are likely to be strong, so please take precautions such as wearing hats and using sunscreen. For more details, please visit our website.

We held the "2nd World Model and Its Surroundings" online, hosted by our company.
