24 == 1.1 What is LoRaWAN Microwave Radar Distance Sensor ==
25
26
27 The Dragino MDS200-LB/LS is a (% style="color:blue" %)**LoRaWAN Microwave Radar distance sensor**(%%). It uses (% style="color:blue" %)**24Ghz Microwave**(%%) to detect the (% style="color:blue" %)**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.
28
29 The MDS200-LB/LS 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.
30
31 MDS200-LB/LS can measure two distances: the closest object and next object behind the closest one.
32
33 MDS200-LB/LS supports (% style="color:blue" %)**Alarm Feature**(%%), user can set the MDS200-LB/LS to uplink data in a short interval when the distance is out of configured range.
34
35 The LoRa wireless technology used in MDS200-LB/LS 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.
36
37 MDS200-LB/LS (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
38
39 MDS200-LB/LS is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery **(%%)or (% style="color:blue" %)**solar powered + li-on battery**(%%) , it is designed for long term use up to 5 years.
40
41 Each MDS200-LB/LS 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.
42
43 *Battery life depends on how often to send data, please see [[battery analyzer>>||anchor="H4.Battery26PowerConsumption"]].

186
187 == 2.1 How it works ==
188
189
190 The MDS200-LB/LS is configured as (% style="color:#037691" %)**LoRaWAN OTAA Class A**(%%) mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the MDS200-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

194 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
195
196
197 Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.
198
199 The LPS8v2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.

469
470
471 Set **PNACKMD=1**, MDS200-LB/LS will wait for ACK for every uplink, when there is no LoRaWAN network, MDS200-LB/LS will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.

In a future uplink if MDS200-LB/LS gets a ACK, MDS200-LB/LS will consider there is a network connection and resend all NONE-ACK messages.

500 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
501
502 Once MDS200-LB/LS Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to MDS200-LB/LS. If MDS200-LB/LS fails to get the time from the server, MDS200-LB/LS will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
503

If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.**
