25 -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.
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.
26 26  
27 -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 
28 -consumption. It targets professional wireless sensor network applications such smart cities, building automation, and so on.
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.
29 29  
30 -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.**
28 +It detects the distance between the measured object and the sensor, and uploads the value via wireless to LoRaWAN IoT Server.
31 31  
32 -DS20L is fully compatible with (% style="color:blue" %)**LoRaWAN v1.0.3 Class A protocol**(%%), it can work with a standard LoRaWAN gateway.
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.
33 33  
34 -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.
