20 The Dragino LLDS12 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.
21
22 The LLDS12 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.
23
24 It detects the distance between the measured object and the sensor, and uploads the value via wireless to LoRaWAN IoT Server.
25
26 The LoRa wireless technology used in LLDS12 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.
27
28 LLDS12 is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
29
30 Each LLDS12 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.

93 == 2.1 How it works ==
94
95 (((
96 The LLDS12 is configured as 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 power on the LLDS12. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
97 )))
98
99 (((
100 In case you can’t set the OTAA keys in the LoRaWAN OTAA server, and you have to use the keys from the server, you can [[use AT Commands >>||anchor="H6.UseATCommand"]]to set the keys in the LLDS12.
