19 (((
20 The Dragino LMDS200 is a (% style="color:#4472c4" %)**LoRaWAN Microwave Radar distance sensor**(%%). It uses (% style="color:#4472c4" %)**24Ghz Microwave**(%%) to detect the distance between sensor and different objects. Compare vs ultrasonic or Lidar measurement method, Microwave Radar is (% style="color:#4472c4" %)**more reliable for condensation / dusty environment**(%%). It can sense correct distance even there is water or thick dust on top of the sensor.
21 )))
22
23 (((
24 The LMDS200 can be applied to scenarios such as horizontal distance measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewer, etc.
25 )))
26
27 (((
28 LMDS200 can (% style="color:#4472c4" %)**measure two distances**(%%): the closest object and next object behind the closest one.
29 )))
30
31 (((
32 LMDS200 supports (% style="color:#4472c4" %)**Alarm Feature**(%%), user can set the LMDS200 to uplink data in a short interval when the distance is out of configured range.
33 )))
34
35 (((
36 The LoRa wireless technology used in LMDS200 allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
37 )))
38
39 (((
40 LMDS200 is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.
41 )))
42
43 (((
44 Each LMDS200 is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

561 LMDS200 supports Alarm Feature, when LMDS200 detect the distance exceed the alarm settings, LMDS200 will Enter Alarm Mode and use the [[ATDC interval>>||anchor="H3.2SetAlarmTransmitIntervalTime280x0D29"]] (default is 1 minute) to uplink Distance value. Alarm mode will last for 60 uplinks (default 1 hour) and can be close by downlink command 0xA300.
