要約(日本語): Infrastructure monitoring systems attract much attention to make the infrastructures robust. These systems enable the appropriate maintenance and management of infrastructure structures for extending their service lifetimes. This paper proposes a multiple-point and real-time underground moisture content monitoring system for achieving robust embankments. The proposed system consists of commercially available and less expensive microcomputers (ESP-32), versatile oscillator circuit boards, homemade capacitive sensors, a Lithium-ion battery, and a 4G Wi-Fi router uploading observed data to an IoT cloud. The power consumption of the 4G Wi-Fi router was dominant. The microcomputer enables the Bluetooth-activated intermittent operation of the 4G Wi-Fi router to reduce its power consumption significantly. The proposed system measured the underground moisture contents of a pseudo embankment constructed at an experimental site in summer. The proposed system operated for at least five days in an outdoor and hot environment. This demonstration confirmed that the proposed system collected data and sent them to the IoT cloud: Ambient.
