Le radon est un \u00e9l\u00e9ment radioactif naturel que l’on trouve en forte concentration \u00e0 proximit\u00e9 des volcans et des gisements d’uranium. Il est l’un des pr\u00e9curseurs potentiels des \u00e9ruptions volcaniques.<\/p>\n

Depuis de nombreuses ann\u00e9es, les scientifiques mesurent le radon sur le sol de l’Etna, \u00e0 3 300m d’altitude, ce qui n\u00e9cessitait, jusqu\u2019alors, de nombreux d\u00e9placements sur place. Ce nouveau r\u00e9seau de capteurs autonomes, con\u00e7u et d\u00e9velopp\u00e9 par des scientifiques fran\u00e7ais, connect\u00e9 \u00e0 un r\u00e9seau LoRaWAN priv\u00e9, doit permettre \u00e0 terme la mesure en continu du radon contenu dans les panaches de gaz volcanique. L\u2019acc\u00e8s aux mesures, quelles que soient les conditions m\u00e9t\u00e9orologiques ou le niveau d\u2019activit\u00e9 et de dangerosit\u00e9 du volcan, est une avanc\u00e9e majeure pour les scientifiques.<\/p>\n

La Wirnet Station<\/a> d\u00e9ploy\u00e9e sur l’Etna collecte les informations issues de capteurs LoRaWAN, qui rel\u00e8vent \u00e9galement un ensemble de donn\u00e9es m\u00e9t\u00e9orologiques, puis les transmet, via son module 3G int\u00e9gr\u00e9, au serveur LoRaWAN de l\u2019Universit\u00e9 de Clermont-Ferrand o\u00f9 les scientifiques y analysent les donn\u00e9es.<\/p>\n

\u00ab Les capteurs de radon transmettent leurs donn\u00e9es en temps quasi r\u00e9el, toute l’ann\u00e9e, au serveur LoRaWAN de Clermont-Ferrand et donnent ainsi aux volcanologues des indications suppl\u00e9mentaires permettant de mieux comprendre la dynamique magmatique et \u00e9ruptive du volcan \u00bb, explique Laurent Royer, du Laboratoire de Physique de Clermont<\/a>, unit\u00e9 de recherche commune de l’Universit\u00e9 de Clermont-Auvergne et du Centre National de la Recherche Scientifique (CNRS).<\/p>\n

\u00ab Ce projet souligne non seulement la diversit\u00e9 et l\u2019importance des cas pratiques d\u2019application des r\u00e9seaux LoRaWAN, et illustre \u00e0 nouveau la position de Kerlink en tant que fournisseur leader de stations robustes et performantes pour tout type de cas d’usage \u00bb, d\u00e9clare St\u00e9phane Dejean, Directeur Marketing et Communication de Kerlink. \u00ab Les stations de la gamme Wirnet rendent possibles beaucoup de projets IoT dans tout type d\u2019environnements y compris les plus difficiles et exigeants du globe. Nos \u00e9quipes sont tr\u00e8s fi\u00e8res de pouvoir contribuer \u00e0 ce type de projet de recherche et de pr\u00e9vention. \u00bb <\/p>\n

Le projet de recherche volcanique a \u00e9t\u00e9 financ\u00e9 par le projet CAP20-25 de l’I-SITE Clermont<\/a> et par le Fonds europ\u00e9en de d\u00e9veloppement r\u00e9gional (FEDER), en partenariat avec l\u2019Institut italien de G\u00e9ophysique et Volcanologie<\/a> (INGV).<\/p>\n
