The Dragino DDS20-LB/LS is a LoRaWAN ultrasonic liquid level sensor designed for Internet of Things (IoT) applications. Utilizing a non-contact method, it measures the height of liquid in a container without the need to open or penetrate the container, ensuring safety and ease of installation. The sensor is installed directly below the container to detect the liquid level, making it ideal for measuring various liquids, including toxic substances, strong acids, strong alkalis, and pure liquids in high-temperature and high-pressure airtight containers. The DDS20-LB/LS employs ultrasonic sensing technology for precise distance measurement and transmits the data via the LoRaWAN network to an IoT server. It supports Bluetooth v5.1 and LoRaWAN remote configuration, as well as wireless over-the-air (OTA) firmware updates, enhancing user convenience. Powered by either an 8500mAh Li-SOCI2 battery (DDS20-LB) or a solar panel combined with a 3000mAh Li-ion battery (DDS20-LS), the device is designed for long-term use of up to 5 years. Each sensor comes pre-loaded with a unique set of keys for LoRaWAN registration, enabling automatic connection after activation.
