Dragino NDDS20 NB-IoT Liquid Level Sensor
The Dragino NDDS20 is a 24GHz radar-based distance and level sensor that provides non-contact measurement for a wide range of applications. With a detection range from 0.3 to 20 meters and ±2 cm accuracy, it excels in tough environmental conditions where ultrasonic sensors may fail. Its low-power design supports long-term operation with an 8500mAh internal battery.
NDDS20 is a great choice for tank level monitoring, silo material tracking, and outdoor environment sensing. It’s particularly effective in dusty, humid, or windy settings where traditional sensors may struggle with reliability.
