Abstract
Nowadays, education on energy saving at schools attracts attention to reduce energy consumption. In this paper we proposed a novel system to promote energy conservation activity at schools using a sensor network. The system consisted of a wall-type clock embedded with several kinds of sensors for temperature and light in the classroom, and wireless devices to connect to a cloud computer network. The system had the following superiorities: offered various services for energy conservation activity, needless of CT (Current Transformer) sensor, low price, ease of installation and extension, and visualization of power consumption in conjunction with school timetable in real time. We presented the system and a user study conducted to evaluate its usefulness.

Summary
In order to reduce electric power consumption, it is necessary to examine our lifestyles and develop awareness of electric power conservation. It has been pointed out that activities to enlighten people on power saving or energy conservation are very important. Educational institutions, such as primary schools and junior and senior high schools, appeal as organizations suited to teaching energy conservation. Some schools set up a smart meter, displaying electric power consumption, allowing school children to check power usage in real time. They could identify potential for saving power in their schools, by becoming aware of energy consumed through their actions. If energy saving activity or education on global warming were more advanced in schools, we could realize huge savings in energy consumption beyond our forecasts
