DDS20-LS LoRaWAN® Ultrasonic Distance Detection Sensor

https://www.aiotkart.com/web/image/product.template/17652/image_1920?unique=e0cbde3

The Dragino DDS20-LS LoRaWAN® Ultrasonic Distance Detection Sensor is a solar-powered, non-contact liquid level monitoring solution designed for industrial IoT deployments. As an Authorized Dragino Distributor in India, AIoTkart® supplies the DDS20-LS for smart tank monitoring, industrial liquid storage management, and hazardous chemical level measurement applications.

The DDS20-LS uses ultrasonic sensing technology to measure liquid height from outside the container. Installed directly below the tank, it detects the liquid level without requiring any hole or direct contact with the liquid. This non-invasive measurement method ensures maximum safety and makes it ideal for toxic substances, strong acids, strong alkalis, liquefied gases, and high-temperature or high-pressure sealed containers.

The integrated solar panel with 3000mAh rechargeable Li-ion battery enables long-term autonomous outdoor operation, making it suitable for remote tank installations and smart city infrastructure.
