DDS20-LS Solar Powered LoRaWAN Liquid Level Sensor

The Dragino DDS20-LS is a LoRaWAN ultrasonic liquid level sensor that uses non contact method to measure the height of liquid in a metal or glass container. The measured values are uploaded wirelessly to the LoRaWAN IoT Server.

The DDS20-LS sensor is installed directly below the container to detect the height of the liquid level. The sensor can be mounted on the outside of the container with glue (not included). It can measure liquid levels up to 2m.

This device supports BLE and LoRaWAN remote configure which makes it very easy to adapt the device. It also supports wireless OTA to update the firmware.

DDS20-LS is powered by a rechargeable battery with solar cell and allows continuous use.

Each DDS20-LS is pre-loaded with a set of unique keys for LoRaWAN registrations. If you register these OTAA keys to the local LoRaWAN server (e.g. TTN), then it will auto connect after power on.
