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	+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.
25	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	+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.
