Dragino DDS20-LB-EU868 LoRaWAN Ultrasonic liquid level sensor

The Dragino DDS20-LB-EU868 is a LoRaWAN ultrasonic liquid level sensor designed for Internet of Things (IoT) applications. It employs a non-contact method to measure the height of liquid in a container without the need to open the container, transmitting the data via LoRaWAN to an IoT server.

Key Features:

• Measures liquid levels from below the container without requiring any openings.
• Ensures safe and easy measurement, ideal for strict or hazardous environments.
• Provides high-accuracy measurements for various liquids, including toxic substances, strong acids, strong alkalis, and pure liquids in high-temperature and high-pressure airtight containers.
• Enables extremely long-range communication with low data rates.
• Offers ultra-long-range spread spectrum communication, high interference immunity, and low current consumption.
• Supports Bluetooth Low Energy (BLE) for easy configuration.
• Allows for wireless Over-The-Air (OTA) firmware updates.
• Powered by an 8500mAh Li-SOCI2 battery, designed for up to 5 years of use.
• Pre-loaded with unique keys for LoRaWAN registration. Register these keys with your local LoRaWAN server for automatic connection upon power-up.

Applications:

• Measuring liquid levels in hazardous or sealed environments
• Monitoring toxic substances, strong acids, and alkalis
• Managing liquid levels in high-temperature and high-pressure containers

The Dragino DDS20-LB-EU868 combines advanced LoRaWAN technology with non-contact ultrasonic sensing, making it an ideal solution for precise and safe liquid level measurement in a variety of IoT applications.
