DRAGINO LMDS200-EU868 distance and level detection

overview

Dragino NMDS200 is an NB-IoT microwave radar distance sensor. It uses 24Ghz microwaves to detect the distance between sensor and different objects. Compared with ultrasonic or lidar measurement methods, microwave radar is more reliable in condensation and dusty environment. It can detect the correct distance even if there is water or thick dust on the sensor.

The NMDS200 can be used in scenarios such as horizontal distance measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewerage, etc.

NMDS200 can measure two distances: the closest object and the next object behind the closest object.

The NMDS200 supports the alarm function. The user can set the NMDS200 to send data at a short interval when the distance is outside the configured range.

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.

NMDS200 supports various uplink methods such as TCP, MQTT, UDP and CoAP for different application requirements.

NMDS200 is powered by a 8500mAh Li-SOCI2 battery, which is designed for long-term use up to 5 years. (The actual battery life depends on the use environment, upgrade period and uplink method)

To use the NMDS200, the user must check if there is NB-IoT coverage in the area and with the Nb-IoT bands that the NMDS200 supports. If the local operator supports it, the user must obtain an NB-IoT SIM card from the operator and install it into the NMDS200 to get NB-IoT network connection.
