++== 1.1 What is LoRaWAN LiDAR ToF Distance Sensor ==
--The Dragino (% style="color:blue" %)**DS20L is a smart distance detector**(%%) base on long-range wireless LoRaWAN technology. It uses (% style="color:blue" %)**LiDAR sensor**(%%) to detect the distance between DS20L and object, then DS20L will send the distance data to the IoT Platform via LoRaWAN.
++The Dragino LDS12-LB is a (% style="color:blue" %)**LoRaWAN LiDAR ToF (Time of Flight) Distance Sensor**(%%) for Internet of Things solution. It is capable to measure the distance to an object as close as 10 centimeters (+/- 5cm up to 6m) and as far as 12 meters (+/-1% starting at 6m)!. The LiDAR probe uses laser induction technology for distance measurement.
--DS20L allows users to send data and reach extremely long ranges via LoRaWAN. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current
--consumption. It targets professional wireless sensor network applications such smart cities, building automation, and so on.
++The LDS12-LB 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.
--DS20L has a (% style="color:blue" %)**built-in 2400mAh non-chargeable battery**(%%) for long-term use up to several years*. Users can also power DS20L with an external power source for (% style="color:blue" %)**continuous measuring and distance alarm / counting purposes.**
++It detects the distance between the measured object and the sensor, and uploads the value via wireless to LoRaWAN IoT Server.
--DS20L is fully compatible with (% style="color:blue" %)**LoRaWAN v1.0.3 Class A protocol**(%%), it can work with a standard LoRaWAN gateway.
++The LoRa wireless technology used in LDS12-LB 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.
--DS20L supports (% style="color:blue" %)**Datalog feature**(%%). It will record the data when there is no network coverage and users can retrieve the sensor value later to ensure no miss for every sensor reading.
++LDS12-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.

++= 2. Configure LDS12-LB to connect to LoRaWAN network =
++== 2.1 How it works ==
--==== (% style="color:blue" %)**Distance**(%%) ====
++The LDS12-LB 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 LDS12-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
--Represents the distance value of the measurement output, the default unit is cm, and the value range parsed as a decimal number is 0-1200. In actual use, when the signal strength value Strength.
++(% style="display:none" %) (%%)
++== 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==
--**Example**:
--If the data you get from the register is 0x0B 0xEA, the distance between the sensor and the measured object is 0BEA(H) = 3050 (D)/10 = 305cm.
++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.
++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.
--==== (% style="color:blue" %)**Distance signal strength**(%%) ====
++[[image:image-20230613140140-4.png||height="453" width="800"]](% style="display:none" %)
--Refers to the signal strength, the default output value will be between 0-65535. When the distance measurement gear is fixed, the farther the distance measurement is, the lower the signal strength; the lower the target reflectivity, the lower the signal strength. When Strength is greater than 100 and not equal to 65535, the measured value of Dist is considered credible.
++(% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from LDS12-LB.
++Each LDS12-LB is shipped with a sticker with the default device EUI as below:
--**Example**:
++[[image:image-20230426084152-1.png||alt="图片-20230426084152-1.png" height="233" width="502"]]
--If payload is: 01D7(H)=471(D), distance signal strength=471, 471>100,471≠65535, the measured value of Dist is considered credible.
--Customers can judge whether they need to adjust the environment based on the signal strength.
