摘要: Systems and methods for sensing environmental changes using electromagnetic interference (EMI) signals are disclosed herein. An EMI monitoring system may be used to monitor an signal of one or more light sources provided over a power line, e.g., in home building. The received energy at the line analyzed detect variations signature indicative occurring proximity sources. Environmental that sensed include, but not limited to, proximity, touch, motion, temperature change.
