Abstract
The method of operation applies to a self-powered home automation sensor device for detecting the existence of and/or for measuring the intensity of a first physical phenomenon, comprising a means of converting an effect of a second physical phenomenon into electrical energy and a means of determining the instantaneous power of this second physical phenomenon that can be converted into electrical energy, wherein a normal, first mode of operation of the device or an energy-saving second mode of operation of the device is activated according to a value defined on the basis of the determination of the instantaneous power that can be converted into electrical energy.
