The Milesight EM411-RDL is a LoRaWAN distance sensor that uses millimeter wave radar technology to reliably measure liquid levels and distances from 0.3 to 12 meters. The robust IP68 PVDF housing protects against dust, water, corrosion, and extreme environmental conditions. The sensor is ATEX-certified for Zone 0 (Ex ia IIC T4 Ga) and can therefore also be used in potentially explosive areas. It offers easy configuration via NFC or Bluetooth, local data storage, alarms for fill level deviations, and enables the transmission of measured values to IoT platforms via LoRaWAN. Thanks to its long-life battery, the device operates autonomously for several years.
