DDS20-NX: NB-IoT Ultrasonic Liquid Level Sensor

The Dragino DDS20-NX is an NB-IoT Ultrasonic liquid level sensor for Internet of Things solutions. It uses a non-contact method to measure the height of liquid in a container without opening the container, and sends the value via the NB-IoT network to an IoT Server.

The DDS20-NX sensor is installed directly below the container to detect the height of the liquid level. Users don’t need to open the container for the level to be measured. The non-contact measurement makes the measurement process safer, easier and possible for some stricter situations.

The DDS20-NX uses ultrasonic sensing technology for distance measurement. The DDS20-NX is of high accuracy to measure various liquids such as: toxic substances, strong acids, strong alkalis and various pure liquids in high-temperature and high-pressure airtight containers.

The DDS20-NX supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirements, and supports uplinks to various IoT Servers.

The DDS20-NX supports BLE configuration and OTA updates which makes the device easy to use.

The DDS20-NX is powered by 8500mAh or 190000mAh Li-SOCI2 battery or solar powered with a 3000mAh Li-ion battery designed for long term use.
