Abstract

L'invention concerne un dispositif de mesure de précipitations comportant un capteur piézoélectrique, un amplificateur piézoélectrique, un convertisseur fréquence-tension, un convertisseur tension-fréquence, un compteur, et une unité centrale. Le capteur piézoélectrique génère des premiers à nième signaux de transformation piézoélectriques en fonction de la pression des gouttes de pluie. L'amplificateur piézoélectrique génère des signaux d'impulsion par amplification desdits signaux de transformation piézoélectriques. Le convertisseur fréquence-tension génère des signaux de tension de mesure en fonction des signaux d'impulsion. Le convertisseur tension-fréquence génère des signaux de fréquence de mesure en fonction des signaux de tension de mesure. Le compteur génère des données de mesure par comptage des signaux de fréquence de mesure pendant une durée prédéfinie. L'unité centrale génère des données de précipitations en fonction des données de mesure. Le dispositif de mesure de précipitations est fabriqué à l'aide d'une structure simple et permet de mesurer avec précision une quantité de précipitations.
