Nowadays, many single-board computers with OS (Operating System) are easily available thanks to IoT (Internet of Things) evolution, and they are utilized for measurement system via the Internet. However, some drawbacks are weakness to fluctuations in power supply such as blackouts, and necessity of additional analog circuits. Our relatively low-cost (6,000 JPY) device achieved sustainable long-term operation by using the microcontrollers, and a promising equipment for room-level monitoring of electricity consumption.}, pages = {106--112}, title = {低コストかつ長期稼働性能を備えた皮相電力計測用マイクロコントローラモジュールの試作}, volume = {30}, year = {2018}, yomi = {オチアイ, タカオ and タケウチ, スミト} }
