26
27
28 The Dragino NDDS75 is a **NB-IOT Distance Detection Sensor** for Internet of Things solution. It is used to measure the distance between the sensor and a flat object. 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.
29
30 It detects the distance between the measured object and the sensor, and uploads the value via wireless to IoT Server.
31
32 **NarrowBand-Internet of Things (NB-IoT)** is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage.
33
34 NDDS75 is powered by 8**500mA Li-SOCI2 battery**; It is designed for long term use up to 5 years*.
35
36 ~* Actually lifetime depends on network coverage and uplink interval and other factors

114 The NSE01 is equipped with a NB-IoT module, the pre-loaded firmware in NSE01 will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module.  The NB-IoT network will forward this value to IoT server via the protocol defined by NSE01.
