21 == 1.1 What is LoRaWAN LiDAR ToF Distance Sensor ==
22
23
24 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.
25
26 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.
27
28 It detects the distance between the measured object and the sensor, and uploads the value via wireless to LoRaWAN IoT Server.
29
30 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.
31
32 LDS12-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
33
34 LDS12-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
35
36 Each LDS12-LB 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.

180
181 == 2.1 How it works ==
182
183
184 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.

191 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.
192
193 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.

361
362 **Example**:
363
364 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.

368
369
370 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.

374
375 If payload is: 01D7(H)=471(D), distance signal strength=471, 471>100,471≠65535, the measured value of Dist is considered credible.

569 The LiDAR probe is based on TOF, namely, Time of Flight principle. To be specific, the product emits modulation wave of near infrared ray on a periodic basis, which will be reflected after contacting object. The product obtains the time of flight by measuring round-trip phase difference and then calculates relative range between the product and the detection object, as shown below.

617 * Measure high reflectivity object such as: Mirror, Smooth ceramic tile, static milk surface, will have possible wrong readings.
618 * While there is transparent object such as glass, water drop between the measured object and the LiDAR sensor, the reading might be wrong.
619 * The LiDAR probe is cover by dirty things; the reading might be wrong. In this case, need to clean the probe.
620 * The sensor window is made by Acrylic. Don't touch it with alcohol material. This will destroy the sensor window.
