Dragino LT Serisi LoRaWAN I/O Controller

Dragino DDS45-LB/LS is a LoRaWAN distance and level detection sensor designed for industrial IoT solutions. Using ultrasonic technology, it measures contactless distance to flat objects between 30 mm and 4500 mm, transmitting data via LoRaWAN network. Built-in temperature compensation, Bluetooth v5.1 support, and wireless OTA firmware updates enable easy setup and remote management. IoTMarketi provides a multi-brand industrial IoT catalog for projects in Turkey; device selection and procurement are managed through project quotation.
