[Introduction]：E95-DTU(400SL22P-485) est un DTU de transmission de données sans fil qui utilise la technologie de modulation LoRa de qualité militaire.La coque adopte un revêtement à trois niveaux : antifongique, anti-humidité et anti-sel. Il existe diverses méthodes de transmission. Il fonctionne sur la bande de fréquence (410/441 M) (433 MHz par défaut). Le DTU fournit une interface RS485 transparente, coque en plastique. Structure d'installation de type rail, prend en charge l'entrée de tension 8 ~ 28 V.
