26 == 1.1 What is LoRaWAN Distance Detection Sensor ==
27
28
29 The Dragino DDS45-LB/LS is a (% style="color:blue" %)** LoRaWAN Distance Detection Sensor**(%%) for Internet of Things solution. It is used to measure the distance between the sensor and a flat object. The distance detection sensor is a module that uses (% style="color:blue" %)** ultrasonic sensing technology**(%%) for (% style="color:blue" %)**distance measurement**(%%), and (% style="color:blue" %)** temperature compensation**(%%) is performed internally to improve the reliability of data. The DDS45-LB/LS can be applied to 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, bottom water level monitoring, etc.
30
31 It detects the distance(% style="color:blue" %)**  between the measured object and the sensor**(%%), and uploads the value via wireless to LoRaWAN IoT Server.
32
33 The LoRa wireless technology used in DDS45-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.
34
35 DDS45-LB/LS (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
36
37 DDS45-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.
38
39 Each DDS45-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.

215 The DDS45-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 DDS45-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

521 Once DDS45-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 DDS45-LB/LS. If DDS45-LB/LS fails to get the time from the server, DDS45-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).

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.**

Some serial tool doesn't send (% style="color:blue" %)**ENTER**(%%) while press the send key, user need to add ENTER in their string.
727
728
729 == 7.3  Why does the sensor reading show 0 or "No sensor" ==
730
731
732 ~1. The measurement object is very close to the sensor, but in the blind spot of the sensor.
733
734 2. Sensor wiring is disconnected

741
742 1) Please check if there is something on the probe affecting its measurement (condensed water, volatile oil, etc.)
743
744 2) Does it change with temperature, temperature will affect its measurement
