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 liquid in a container without opening it, sending the value via the LoRaWAN network to an IoT server.

The LDDS20 sensor is installed directly below the container to detect the liquid level. Users do not need to create an opening in the container being tested. The non-contact measurement ensures safety and ease of use, making it suitable for strict situations.

The LDDS20 employs ultrasonic sensing technology for distance measurement and is highly accurate in measuring various liquids, including toxic substances, strong acids, strong alkalis, and various pure liquids in high-temperature and high-pressure airtight containers.

The LoRa wireless technology used in the LDDS20 allows the device to transmit data over extremely long ranges at low data rates. It provides ultra-long-range spread spectrum communication and high interference immunity while minimizing current 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-loaded with a set of unique keys for LoRaWAN registration. Users can register these keys to a local LoRaWAN server, and the device will automatically connect if there is network coverage after being powered on.
