Abstract

La présente invention concerne un procédé et un dispositif capteur conçus pour surveiller l'état et la position de marchandises (30). Le procédé est mis en œuvre par un dispositif capteur (10) et comprend une étape consistant à recevoir (S500) des données de configuration qui contiennent des paramètres à surveiller, des intervalles de surveillance et des seuils de paramètres. Le dispositif capteur (10) collecte (S502) des données de paramètres en fonction des intervalles de surveillance paramétrés, détermine (S504) qu'une valeur actuelle des données de paramètres dépasse au moins un des seuils de paramètres et détermine (S506) la position actuelle. Lorsque la position a été déterminée, le dispositif capteur (10) balaie (S508) des bandes de communication sur la base de la position actuelle déterminée, se connecte (S510) à la bande de communication permettant la communication la plus économe en énergie et envoie (S516) à un nœud de surveillance (40) une alerte indiquant qu'au moins un seuil de paramètre a été dépassé.
