We exhibited at the Tokushima ICT Bazaar VOL. 5 related to IoT.

It is ideal for rainfall measurement in municipal disaster prevention systems and pinpoint rainfall monitoring for companies. Our engineers will flexibly handle data integration with external systems.

This is our in-house developed "IoT Rain Gauge" system. You can view the data on the cloud. The IoT rain observation system sends the rainfall data counted by the tipping bucket rain gauge to the IoT platform (cloud system) via a dedicated IoT wireless protocol. The transmitted rainfall data can be checked on a dashboard displayed in a web browser. It is also compatible with data integration with our "Pond Monitoring Device." When the rainfall reaches a predetermined hazardous level, an alert notification is sent, allowing for preparations in advance of heavy rainfall and other events. The data accumulated in the cloud can be exported as a CSV file and used for analysis, forecasting, and prediction. The observation device can be powered by solar panels and batteries, making it possible to install in locations where power supply is difficult, and it can operate even during power outages. *For more details, please contact us via the IPROS inquiry form or by phone. *Mentioning "I saw it on IPROS" will facilitate a smoother explanation.

Ideal for monitoring water levels in small rivers, waterways, and ponds. Achieves overwhelming low cost compared to conventional products. Offers a lineup of primary batteries, solar power, etc.

This is an IoT system developed in-house to monitor water levels in "small rivers and waterways." It is also ideal for monitoring disaster prevention priority ponds (with camera and solar power options available). The IoT ultrasonic water level monitoring sensor emits ultrasonic waves and measures the water level based on the time it takes for the reflected waves to return to the transmitter. Data accumulated in the cloud allows for quantitative understanding of water level trends in rivers, ponds, agricultural waterways, etc., contributing to crisis management as well. The device itself is powered by solar panels and batteries, making it possible to install in locations where power supply is difficult, and the remaining battery level can be checked on the dashboard, allowing for advance notice of battery replacement timing. [Applications] - Water level observation and monitoring for rivers, agricultural waterways, ponds, etc. *For more details, please contact us via the IPROS inquiry form or by phone. *Mentioning "I saw it on IPROS" will facilitate a smoother explanation.

An article has been published about the case of introducing the expense reimbursement system "Rakuraku Seisan" at TSP Corporation. ~ In the case of TSP ~ Before the introduction, there were challenges such as dealing with the "paper" sent from various locations and the reliance on specific individuals for the tasks. After the introduction, the input and checking of FB data, which used to take 2 to 3 hours, can now be completed in just 5 minutes. Additionally, the mindset of the accounting department, which was previously reliant on manual entry, has changed. [Case Overview] ■ Challenges before introduction - Dealing with "paper" sent from various locations, reliance on specific individuals ■ Key points of introduction - A robust support system for setup and operation - Easy to start from a small scale both financially and functionally *For more details, please refer to the related links or feel free to contact us.

The facility operating the nurse call system has made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call. 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. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call. ○ 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.

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8

Castem Co., Ltd. will exhibit at the "Monozukuri World Osaka - Mechanical Components Technology Exhibition" held at Intex Osaka from Wednesday, October 1 to Friday, October 3, 2025.
