overview

The Dragino NDDS75 is an NB-IoT distance detection sensor for Internet of Things solutions. It is designed to measure the distance between the sensor and a flat object. The distance detection sensor is a module that uses ultrasonic technology to measure distance, and temperature compensation is performed internally to improve the reliability of the data.

The NDDS75 can be used in 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, groundwater level monitoring, etc. It detects the distance between the measured object and the sensor and uploads the value to the IoT server wirelessly via the NB-IoT network.

NarrowBand Internet of Things (NB-IoT) is a standards-based low-power wide-area (LPWA) technology designed to enable a wide range of new IoT devices and services. NB-IoT significantly improves user device power consumption, system capacity, and spectrum efficiency, especially in deep coverage.

The NDDS75 supports various uplink methods such as TCP, MQTT, UDP and CoAP for different application requirements.

The NDDS75 is powered by a 8500mAh Li-SOCI2 battery, which is designed for long-term use up to 5 years. (The battery life depends on the use environment, update time and uplink method)

To use the NDDS75, the user needs to check if there is NB-IoT coverage in their area and which bands the NDDS75 supports. If the local operator supports it, the user needs to obtain an NB-IoT SIM card from the local operator and install the NDDS75 to get NB-IoT network connection.
