Smart nanogrid technologies such as smart home and smart shelters are under development in the current power and energy systems. In smart nanogrids, presence sensors play an essential role to detect human-being presence in room to control the operation of power devices like air conditioners automatically, and thus save power usage and electric bills. In this study, we field-tested the performance of X4M300 presence sensor for human-being detection and power device control. This presence sensor has a notable capability to detect living beings according to the movement of their breathing. In principle, this presence sensor is more reliable than PIR detectors, which are used to determine presence by using infrared light. For the presence sensor, the maximum range of detection is 10 meters, which can be adjusted by changing its settings via the Xethru explore software.
