Discussed here is the experiment of power monitoring using new wireless sensor nodes in home, business, data-center, and commercial areas. From these experiments, we confirmed the ease of our monitoring system installation, and the stability of receiving data from a high number of sensor-nodes. The power “profile” of equipment obtained in several kinds of areas effectively presented the key features of equipment-usage. It would be possible to reduce the waste of power consumption by regularly observing the power “profile” every day and making comparisons between similar sites or equipment. The preference test for our monitoring system presented the possibility of our sensor-nodes being accepted in the home. However, in order to widely distribute our wireless sensor-nodes, it will be essential to achieve “maintenance-free” and “low-cost” sensor-nodes.
