LDDS20 - LoRaWAN Waterproof Liquid Level Sensor

The Dragino LDDS20 LoRaWAN Ultrasonic Liquid Level Sensor uses a non-contact method to measure the height of liquid in a container, without having to open the container. The sensor can be installed directly below the container without a hole, so it is perfect for measuring toxic substances, strong acids, strong alkalis and various pure liquids in high pressure and high temperature air tight containers.


Please note that all LoRaWAN IoT Sensor nodes supplied by Telemetry2U will work with 3rd party network/application servers, like TTN, but if you would like to use your sensors on Telemetry2U’s advanced, plug-and-play IoT Platform, then you will need to purchase a license by selecting from the drop-down box below. Products purchased with a license will be shipped with the latest firmware and configuration optimised for T2U, with no programming or set-up required.

The Dragino LDDS20 is a long range LoRaWAN node that provides spread spectrum communication and high interference immunity whilst minimising power consumption. Its IP68 waterproof design makes it suitable for outdoor use and its powered by a 8500mA Li/SOCl2 non-rechargeable battery. Due to its low power operation, users can expect years of operation with a moderate logging rate. 

The ultrasonic sensor can be installed directly underneath a glass or plastic container with no direct contact, making it ideal for dangerous substances.  The sensor is on a 25cm cable and has a measurement range from 20mm - 2000mm with 5mm accuracy.

It has a user programmable threshold so that you will be immediately informed if you sensor drifts past that threshold.  When used with Telemetry2U, you can receive these alerts via Email, SMS or via an interactive voice call, ensure you assets have the ultimate level of protection.

The Dragino LDDS20 can be configured with downlink commands or alternatively, you can configure your device with a FT232RL USB to TTL converter.
