DRAGINO LDDS20-EU868
Overview
The Dragino LDDS20 is a LoRaWAN ultrasonic liquid level sensor for the Internet of Things solution. It non-contactly measures the height of the liquid in a container without opening the container and sends the value to the IoT server via the LoRaWAN network. The LDDS20 sensor is installed directly under the container to detect the height of the liquid level. The user does not need to open a hole on the container to be tested. Non-contact measurement makes measurement safe, easier and possible for some strict situations. The LDDS20 uses ultrasonic sensor technology to measure distance. LDDS20 is of high accuracy for measuring various liquids such as: toxic substances, strong acids, strong alkalis and various pure liquids in high temperature and high pressure airtight containers. The wireless LoRa technology used in the LDDS20 allows the device to send data and achieve extremely long ranges at low data rates. It offers extremely long-range spread spectrum communication and high interference immunity with minimal power consumption. The LDDS20 is powered by an 8500mA Li-SOCI2 battery and is designed for long-term use of up to 10 years*. Each LDDS20 comes pre-installed with a set of unique keys for LoRaWAN registration. These keys are registered on the local LoRaWAN server and automatically connected after power on if there is network coverage.
