[DDS20-LB] LoRaWAN Ultrasonic liquid level sensor

The Dragino DDS20-LB is a LoRaWAN Ultrasonic liquid level sensor for Internet of Things solution. It uses none-contact method to measure the height of liquid in a container without opening the container, and send the value via LoRaWAN network to IoT Server.

The DDS20-LB sensor is installed directly below the container to detect the height of the liquid level. User doesn't need to open a hole on the container to be tested. The none-contact measurement makes the measurement safety, easier and possible for some strict situation.  

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

The LoRa wireless technology used in DDS20-LB allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

DDS20-LB supports BLE configure and wireless OTA update which make user easy to use.

DDS20-LB is powered by 8500mAh Li-SOCI2 battery , it is designed for long term use up to 5 years.

Each DDS20-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.
