METHOD FOR OPERATING AN AUTONOMOUS SENSOR DEVICE FOR HOME USE FOR DETECTING THE EXISTENCE AND / OR FOR MEASURING THE INTENSITY OF A PHYSICAL PHENOMENON

摘要

The method involves activating a normal operation mode of an autonomous home automation sensor device or an energy saving operation mode of the sensor device according to a value defined from determination of instantaneous power convertible into an electrical energy. The sensor device has reduced electrical consumption in the energy saving operation mode than in the normal operation mode. Measurement frequency of intensity of a physical phenomenon e.g. luminosity, is high in the normal operation mode than in the energy saving operation mode.
