Description
The Dragino NDDS20 is an NB-IoT distance detection sensor designed for IoT solutions. It measures the height of a liquid in a container without needing to open it. The sensor is attached directly below the container, making non-contact measurements both safely and easily.
The NDDS20 uses ultrasonic sensing technology with temperature compensation performed internally to provide reliable and accurate distance measurements.
Using NB-IoT technology, the NDDS20 has significantly reduced power consumption and increased efficiency, most notably in areas with deep coverage. The NDDS20 is powered by an 8500 mAh Li-SOCl₂ battery designed for long term use.
