Abstract

Le problème décrit par la présente invention est d'obtenir une unité d'indice environnemental qui permet de régler automatiquement la température à l'intérieur d'une étable, l'humidité à l'intérieur de l'étable, la vitesse de l'air soufflant sur le bétail, la concentration en CO2 à l'intérieur de l'étable, et la concentration en NH3 à l'intérieur de l'étable, et de s'assurer ainsi que le bétail ne ressente pas d'inconfort. La solution selon l'invention porte sur une unité d'indice environnemental (100) qui est pourvue : d'un capteur d'indice environnemental (80) qui est équipé d'un capteur de température (81) et/ou d'un capteur d'humidité (82) et/ou d'un capteur de vitesse du vent (83) et/ou d'un capteur de concentration en CO2 (84) et/ou d'un capteur de concentration en NH3 (85) ; et d'une unité de commande (90) qui régule la température, l'humidité et la vitesse du vent à l'intérieur d'une étable de sorte que l'indice de température-humidité s'approche d'une valeur souhaitée, et qui commande la ventilation à l'intérieur de l'étable de sorte que la concentration en CO2 et la concentration en NH3 soient inférieures ou égales à une valeur seuil.
