17 -The Dragino NMDS200 is a(% style="color:blue" %)** NB-IoT Microwave Radar distance sensor**(%%). It uses (% style="color:blue" %)**24Ghz Microwave**(%%) to detect the distance between sensor and different objects. Compare vs ultrasonic or Lidar measurement method, Microwave Radar is (% style="color:blue" %)**more reliable for condensation / dusty environment**(%%). It can sense correct distance even there is water or thick dust on top of the sensor.

It detects door (% style="color:blue" %)**open/close status**(%%) and (% style="color:blue" %)**uplinks**(%%) to IoT server via NB-IoT network. NDS03A can connect two door sensors. user can see the door status, open duration, open counts in the IoT Server.

27 +(((
28 +The NDS03A will send periodically data (% style="color:blue" %)**every 4 hours** (%%)as well as for each door open/close action. It also counts the door open times and calculates the last door open duration. Users can also disable the uplink for each open/close event, instead, NDS03A can count each open event and uplink periodically.
