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

The Dragino LDDS20 is a LoRaWAN ultrasonic liquid level sensor designed for Internet of Things solutions. It uses a non-contact method to measure the height of liquids in a container without opening it, and transmits the value via the LoRaWAN network to an IoT server.

The LDDS20 sensor is installed directly under the container to capture the liquid level. Users do not need to create an opening in the container being tested. The non-contact measurement ensures safety and user-friendliness, making it suitable for stringent applications.

The LDDS20 utilizes ultrasonic sensor technology for distance measurement and is highly accurate in measuring various liquids, including toxic substances, strong acids, strong bases, and various pure liquids in high-temperature and high-pressure dense containers.

The LoRa radio technology used in the LDDS20 allows the device to transmit data over extremely long distances at low data rates. It provides ultra-long-range spread spectrum communication and high resistance to interference while minimizing 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. Users can register these keys with a local LoRaWAN server, and the device will automatically connect when network coverage is available after being powered on.
