笳Weathernews and OMRON develop a sensing device that leverages their strengths
In recent years, various companies have increasingly required observation data as a measure to reduce disaster risks. It is difficult to introduce conventional observation equipment due to the time and effort required for installation and budgetary constraints. Therefore, there is a demand for weather sensors that are compact, easy to install, and inexpensive to obtain observation data. Weathernews' founding philosophy is "help people in times of need" and OMRON's commitment is "solving social issues through business". The two companies share many things in common, so we have collaborated on the development of sensing devices since 2017. In the past, Weathernews has launched "WxBeacon2"*2, a compact weather sensor that utilizes OMRON's sensing technology and had been well received by users. This time, OMRON and Weathernews have developed a new solution to meet corporate needs by leveraging the strengths of both companies.

笳High-performance weather IoT sensor "Soratena Pro"
"Soratena Pro" is a high-performance weather observation equipment that can observe seven elements every minute: air temperature, humidity, atmospheric pressure, rainfall amount, wind direction, wind velocity, and illuminance. Conventional observation equipment had the problem of being time-consuming to install because of its large size and the need for line maintenance, but "Soratena Pro" is compact and easy to install, and observation can be started simply by turning on the power. "Soratena Pro" is also useful for the observation of heavy rain and strong winds, which pose a high risk of disaster, because it can accurately observe torrential downpours with a rainfall amount of 50 mm/h and violent storms with a wind velocity speed of 50 m/s using OMRON's advanced sensing technology. Furthermore, by linking with the "weathernews" application, various kinds of weather information including observation data can be checked with one application. The observation data is stored in the cloud and can be provided via API, etc., so companies can acquire observation data via the cloud and incorporate it into their own systems.

笳Check observation data with the highest weather forecast accuracy application
In order to make it easier for you to incorporate observation data into your business, Weathernews has linked "Soratena Pro" with the 窶忤eathernews" application which boasts a cumulative total of 35 million downloads and has the highest weather forecast accuracy. This allows you to use the weather application that is used by many users on a daily basis without changing anything for your business. Just by logging in with your company account, a dedicated page will be displayed on the top page "My Weather".

Check observation data with the highest weather forecast accuracy application01

On the dedicated page, seven types of observation data can be viewed in real time and past data can be checked in graphs. Furthermore, push notifications will be sent out when the observed value exceeds the threshold value. Users can select two elements from air temperature, rainfall amount, and wind velocity, and set the thresholds and titles. By predetermining actions to be taken in response to notifications, companies can respond quickly to heavy rain, strong winds, and high/low air temperatures.

In addition, paid contents for general use, such as raincloud radar and notification functions, are available without advertisements. The weather content of the highest weather forecast accuracy application and the observation data of "Soratena Pro" are provided on the same platform, so you can seamlessly check the weather information useful for your business with one application.

One of the most popular paid features of the application is the "Raincloud radar," which allows you to check data every 10 minutes for up to 30 hours ahead with ultra-high resolution of 250m-mesh. In addition, an extensive range of disaster prevention information is available, including "Multiple typhoon track forecasts" and "Blackout risk predictions," both of which are useful when typhoons are approaching, and "Heavy snow pinpoint," which provides snow accumulation and freezing forecasts during heavy snowfall. Furthermore, push notifications can be sent out to the current location or to up to 20 registered locations for alerts, earthquakes, lightning strikes, tornadoes, etc.

笳Dedicated websites for PC version empowering data analysis are available
Dedicated websites for PC version provide weather information along with real-time video footage and past observation data. Users can specify the month and date to check daily and minute-by-minute observation data in graphs. All observation data from the date of installation up until now are stored in the cloud, and the data can be downloaded in CSV format. Past data for rain clouds, wind direction, and wind velocity up to 24 hours ago and forecast data up to 72 hours ahead can be displayed on a map. Using dedicated websites for PC version is recommended when analyzing the observation data against the damage situation, or when monitoring the data on a display in an office or other locations.

笳Utilize observation data for business
Observation data of 窶彜oratena Pro" can be used for safety measures and productivity improvement in agriculture, construction, drones, logistics, sports, electric power, food retail, apparel, and many other industries. For example, in the field of agriculture, it can be used when there are strong winds to inspect if vegetables have fallen over or if vinyl has been blown away. At construction and building sites, observation data is useful for judging the feasibility of construction works such as high-altitude work and concrete placement during rainfall, of crane work during strong winds, and of preventative measures against heat strokes for workers. 窶彜oratena Pro," which can measure wind velocity accurately just by turning on the power, can also contribute to the realization of drone logistics, in which the flight location changes from time to time. In the case of campsites, installing 窶彜oratena Pro窶 on the premises and monitoring the wind velocity can help prevent fires caused by campers' bonfires. Temperature alert notifications are effective in preventing heat stroke for students in physical education classes and sports meetings, and in preventing heat exhaustion for staff members, visitors, and athletes at zoos, firework displays, and marathon races.
For the electricity market, the system can be installed at solar power plants that do not have solar radiation meters, and power producers can incorporate a solar radiation estimation calculated by Weathernews based on illuminance data which will help improve accuracy of their solar power generation forecasts or to determine power plant failures by comparing with actual power generation.
In the food retail industry such as supermarkets and the apparel industry, the number of customers changes depending on the weather and air temperature, so understanding the weather outside the store can be applied to appropriate staffing and demand forecasting. By linking observation data to the system, digital marketing, such as signage linked to outside weather and coupon distribution via applications, will become possible. In this way, please utilize various types of observation data depending on the intended use of each company.
