Abstract

The invention relates to a passive rain gauge with a very low level of electrical consumption. A very thin fabric is inserted into a rectangular support provided with vent holes all over the surface thereof. Said holes expose the fabric inside the support. Two electrodes are attached to the two ends of the support and are in contact with the fabric.

Description

Détecteur pluviométrique à faible consommation électrique  Rain sensor with low power consumption
Description  Description
L'invention est un capteur de pluie.  The invention is a rain sensor.
Il existe divers dispositifs de pluviomètres qui fournissent des informations relatives à la quantité de pluie, sa direction, sa durée, etc. Ces pluviomètres utilisent des mécanismes qui ne sont pas adaptés lorsque l'économie d'énergie est primordiale et la seule information recherchée est s'il pleut ou non. There are various rain gauge devices that provide information about the amount of rainfall, its direction, duration, and so on. These rain gauges use mechanisms that are not suitable when energy saving is paramount and the only information sought is whether it rains or not.
Suite au développement des énergies renouvelables (solaire, éolienne, etc), plusieurs dispositifs sont conçus et développés pour être autonomes et tirer toute l'énergie dont ils ont besoin uniquement des sources renouvelables. La difficulté principale dans le développement de ces systèmes autonomes est la faible quantité d'énergie dont ils disposent, d'où un souci d'optimisation continue de la consommation en énergie de leurs composants.  Following the development of renewable energies (solar, wind, etc.), several devices are designed and developed to be autonomous and draw all the energy they need from renewable sources only. The main difficulty in the development of these autonomous systems is the small amount of energy they have, hence a concern for continuous optimization of the energy consumption of their components.
Notre invention consiste en un pluviomètre qui consomme le minimum d'énergie possible pour savoir s'il pleut ou pas. Il est constitué d'un support rectangulaire (4) en PPMA  Our invention consists of a rain gauge that consumes as little energy as possible to know if it is raining or not. It consists of a rectangular support (4) made of PPMA
(Polyméthacrylate de Méthyle) appelé aussi plexiglas qui représente l'avantage de la stabilité, de la résistance aux ultraviolets et ne représente aucun risque d'augmentation d'opacité. Ce type de matériau est une référence aujourd'hui sur le marché pour l'utilisation à l'extérieur. Le support rectangulaire est plié en deux et doté de trous d'aération (3) disposés uniformément dans toute sa surface. Un tissu (2) très fin, perméable et absorbant est inséré entre les deux plaques superposées (surfaces de plie) couvrant toute leur surface. Les trous d'aération exposent le tissu contenu entre les deux plaques. Deux électrodes (1) sont disposées aux extrémités du support et sont en contact avec le tissu de sorte que lorsque le tissu est mouillé par l'eau de pluie, la résistance entre les électrodes diminue pour faire passer le courant indiquant que la pluie tombe. Une électrode est alimentée en continu et grâce à un circuit intégré, nous convertissons le signal délivré par le capteur (analogique ; valeur de résistance) en un signal numérique (0,1). (Polymethacrylate Methyl) also called plexiglass which represents the advantage of stability, resistance to ultraviolet and poses no risk of increased opacity. This type of material is a reference on the market today for outdoor use. The rectangular support is folded in two and has ventilation holes (3) uniformly arranged throughout its surface. A very thin, permeable and absorbent fabric (2) is inserted between the two superimposed plates (plaice surfaces) covering their entire surface. The ventilation holes expose the tissue contained between the two plates. Two electrodes (1) are arranged at the ends of the support and are in contact with the tissue so that when the fabric is wet with rainwater, the resistance between the electrodes decreases to pass the current indicating that the rain is falling. An electrode is fed continuously and thanks to an integrated circuit, we convert the signal delivered by the sensor (analog, resistor value) into a digital signal (0,1).
