グリーンハウス List of Products and Services

Information from slope sensors installed on slopes and inclined surfaces is collected via the "LoRaWAN network," a new wireless communication technology, and sent to a cloud data center. This allows for monitoring the status of each sensor from a computer or smartphone, reducing the burden of patrol duties. Additionally, in the event of rainfall or earthquakes that pose a risk of slope failure, alerts are immediately sent to the administrator, enabling quick decision-making from a safe location without the need to visit the site directly. Furthermore, to capture changes in the slope comprehensively, it is necessary to install a large number of multi-point (scatter-type) sensors on the slope. By leveraging the procurement network that Greenhouse has developed over many years, we have achieved practical accuracy and the functionalities required by many operators while reducing total cost of ownership (TCO). In addition to monitoring slope failures, it is also possible to download measurement values, making it useful as documentation and deliverables for routine inspections, such as ground inspection logs and weather observation records. *We offer a cloud service that allows you to monitor sensor information from a dedicated site.

As sudden and localized disasters described as "the largest in recorded history" and "once in 50 years" occur, monitoring of reservoirs and rivers is becoming increasingly important. Therefore, by installing measuring devices (monitoring posts) in more rivers, we have combined the latest technologies such as ICT and IoT with existing elemental and general-purpose technologies to accurately grasp flood situations and quickly and accurately understand the anticipated impacts, thereby achieving a solution that reduces not only the introduction costs but also the TCO (total cost of ownership). The measurement data collected from the devices is uploaded to the cloud via LoRaWAN, and when thresholds are exceeded, notifications are sent to registered email addresses. Additionally, it is possible to monitor in real-time through a web browser and download measurement values, allowing for the confirmation of multiple sensor readings from a distance. This not only reduces the time staff need to physically visit locations at risk of flooding during heavy rain or earthquakes but also eliminates the risk of staff being affected while on patrol.

This system boasts a higher measurement accuracy compliant with Class 1.5 than the inexpensive Class 2 simple heat stroke index meter, measuring and recording five items that serve as indicators for heat stroke prevention: "Heat Index (WBGT)," "Ambient Temperature," "Relative Temperature," "Black Globe Temperature," and "Wet Bulb Temperature." Measurement data can be displayed directly on WBGT displays via LoRa communication, or using LoRaWAN, data uploaded to the cloud can notify registered email addresses when approaching dangerous conditions. Additionally, it allows for real-time monitoring via web browsers and downloading of measurement values, enabling the confirmation of multiple sensor measurements from a distance. Furthermore, due to LoRaWAN communication, there are no restrictions on the number of transmissions, allowing for real-time measurements at one-minute intervals to respond immediately to changes in heat stroke risk. *We also offer a cloud service that allows you to monitor sensor information from a dedicated site.

"GH-EVARDLRA" is a uniquely developed evaluation board product designed to leverage the knowledge and experience of LoRa and LoRaWAN that has been cultivated over many years as the sixth member of the LoRa Alliance in Japan, based on the requests of our partners. It aims to enable businesses participating in concept verification to realize their ideas and business models affordably and in small quantities. The board integrates the LoRaWAN communication chip (GH-WM92LRA) necessary for data communication and a microcontroller (ATmega328PB) for hardware control into a single unit, designed as an Arduino-Nano compatible specification that is familiar to a wide range of developers as open source. Engineers building hardware can easily expand functionality by simply stacking modules with devices such as sensors that are required for commercially available shields, significantly shortening development time while meeting various hardware requirements. Additionally, on the software side, development can be carried out using Arduino-IDE, allowing for easy environment setup by referencing sample code available worldwide, even without specialized technical knowledge.
