Problems solved by technology

In order to avoid this inconvenience, it is possible to have this incidental energy source integrated in the sensor-transmitter (consisting, for example, of a dry cell, which is only used for the first charge at installation), but this would lead to prohibitive costs

no. 1 approach

[0029] Assume that the controlled switch TR is initially open and that the photovoltaic panel is illuminated by light. Under these conditions, capacitor C1 is charged. A start-up event labeled VDDH is when the voltage VCC crosses a voltage threshold that becomes sufficient to power the logic processing unit. This event determines the entry into the first test step T11 for the state of an initialization indicator INIT. In a protected part (of the EEPROM type) of the internal memory of the logical processing unit CPU, the indicator is read.

[0030] If the initialization indicator INIT is not active, the programming process begins with test step T12 (left side of FIG. 2 ). If the initialization indicator is active, enter the transitional operation process (right side of FIG. 2 ) which starts with step E13.

[0031] This programming process allows the sensor-transmitter to be adjusted and matched to other devices in the facility with which it is to communicate. The transient ...

Abstract

The sensor-transmitter (10) has a unit (PVU) converting a certain energy into electrical energy, and an electrical energy storing device (C1, C2) which supplies power to a physical quantity detecting and / or measuring device and a radio frequency signal emitting unit, the radio frequency signal emitting unit (RFU) transmits the information of the physical quantity to the house automation management technology device. The sensor-transmitter (10) is characterized in that the electrical energy storing device comprises an electrical energy storing principal element (C2) and an electrical energy storing assistant device (C1), and the electrical energy storing device also comprises a controlled switch (TR) which is connected in parallel with the principal element and the assistant device.

Description

technical field [0001] The invention relates to an autonomous sensor-transmitter as defined in the preamble of claim 1 . The invention also relates to a method for operating such a sensor-transmitter. Background technique [0002] Known sensor-transmitters according to the prior art comprise an autonomous power supply by converting energy supplied by a certain energy source into electrical energy. The energy source may especially be of electromagnetic type (solar radiation) or mechanical type (rotation or vibration of a structure under the action of wind or rain). This electrical energy is then stored in a usually physicochemical storage device, such as a battery pack, or preferably a supercapacitor, or simply a capacitor. [0003] A sensor-transmitter includes a device that transmits a wireless communication signal via electromagnetic waves, such as via radio waves. The transmission means allow the sensor to transmit information to various other devices of the home autom...
