Abstract (en)
[origin: WO2022195201A1] The invention relates to a method for transmitting a message intended to enable the detection of the absence of a physical element (EM) in a geographical zone (ZG), said physical element being able to be associated with a first/second state (ST_1, ST_2) in which it is present in/absent from said zone, such that a transmitting device (D_TX) is deprived of illumination/is illuminated. Said method is implemented by the transmitting device when the physical element passes from the first state to the second state, and comprises the steps of: - obtaining (E10) an electrical energy reserve (RES_ELEC) from light energy, - comparing (E20) the amount of electrical energy stored with a given threshold (TH), - when said threshold is exceeded, transmitting (E30) a message (MESS_INFO) which is representative of said threshold being exceeded, said transmitting step being implemented using the stored electrical energy.
