LoRaWAN Non Conct Liquid Level Sensor
LDDS20
OVERVIEW:
The Dragino LDDS20 is a LoRaWAN Ultrasonic liquid level sensor for Internet of Things solution.
It uses non 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 LDDS20 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 non contact measurement
makes the measurement safety, easier and possible for some strict situation.
LDDS20 uses ultrasonic sensing technology for distance measurement. LDDS20 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 LDDS20 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.
LDDS20 is powered by 8500mA Li-SOCI2 battery; It is designed for long term use up to 10 years*.
Each LDDS20 pre-loads with a set of unique keys for LoRaWAN registration, register these keys to
local LoRaWAN server and it will auto connect after power on.
