The distance detection sensor is a module that uses **ultrasonic sensing technology** for **distance measurement**, and temperature compensation is performed internally to improve the reliability of data. The NDDS75 can be applied to scenarios such as horizontal distance measurement, liquid level measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewer, bottom water level monitoring, etc.
