Internet of Things (IoT), where physical objects are connected and data of many kinds of sensors are collected over the Internet, becomes one of important social infrastructure technologies. Various sorts of data collection experiments through many kinds of network technologies in many areas have been implemented to improve services and solve problems in the community through uses and applications of the collected data. We are conducting environmental data monitoring experiments using private LoRa, which is one of the low-power wide area (LPWA) communication technologies, BLE and LTE over Chikuma city, Nagano prefecture, Japan. We recently abolished the LoRa relay station on the Koshoku governmental building which was one site of 10 LoRa relay stations and set up 5 new LoRa relay stations, resulting to 14 LoRa relay stations. The LoRa relay stations have Cameras, and high-quality images including short-time movies are transferred (Fig.1). Vaisala Weather stations are set near the all relay stations and weather data are transferred by LoRa. A few tenths of small environmental sensors are set in Togurakamiyamada Junior High School. The environmental data from these sensors are connected to the Data Cloud by BLE to LTE relay stations. Data are monitored in quasi-real time over the Internet and the various sensors are controlled over the Internet. Many kinds of sensors could be connected through this sensor network and some sensors of private companies are used in the network. A LoRa relay station has been set at Shinshu University Faculty of Engineering in Nagano city. We expect that this sensor network will be expanded and used for more applications.
