LDDS20 LoRaWAN Liquid Level Sensor is installed directly below the container to detect the height of the liquid level. The user doesn’t need to open a hole in the container to be tested. The non-contact measurement makes the measurement safety easier and possible for some strict situations.
LDDS20 LoRaWAN Liquid Level Sensor uses ultrasonic sensing technology for distance measurement. LDDS20 is of high accuracy to measure various liquids 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 the 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 LoRaWAN Liquid Level Sensor is powered by an 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 registrations, register these keys to the local LoRaWAN server and it will auto-connect if there is network coverage, after power on.
*Actually lifetime depends on network coverage and uplink interval and other factors
