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. DS20L can measure range between 3cm ~~ 200cm.
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.
