DRAGINO - Sensor - LoRa - LoRaWAN Liquid Level Sensor - LDDS20-EU868

DRAGON LDDS20-EU868

overview

Dragino LDDS20 is a LoRaWAN ultrasonic liquid level sensor for Internet of Things solution. It non-contact measures the height of liquid in a container without opening the container and sends the value to the IoT server via LoRaWAN network. LDDS20 sensor is installed directly under the container to detect the height of liquid level. Users do not need to open a hole on the container to be tested. Non-contact measurement makes measurement safe, easier and possible for some strict situation. LDDS20 uses ultrasonic sensor technology for distance measurement. LDDS20 is of high accuracy for measuring various liquids such as: toxic substances, strong acids, strong alkalis and various pure liquids in airtight high temperature and high pressure containers. The wireless LoRa technology used in LDDS20 enables the device to send data and achieve extremely long ranges at low data rates. It provides 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-up when there is network coverage.
