--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.
++The Dragino DDS20-LB is a (% style="color:blue" %)**LoRaWAN Ultrasonic liquid level sensor**(%%) for Internet of Things solution. It uses (% style="color:blue" %)**none-contact method **(%%)to measure the (% style="color:blue" %)**height of liquid**(%%) in a container without opening the container, and send the value via LoRaWAN network to IoT Server.
--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.
++The DDS20-LB sensor is installed directly below the container to detect the height of the liquid level. User doesn't need to open a hole on the container to be tested. The none-contact measurement makes the measurement safety, easier and possible for some strict situation.
--It detects the distance between the measured object and the sensor, and uploads the value via wireless to LoRaWAN IoT Server.
++DDS20-LB uses (% style="color:blue" %)**ultrasonic sensing technology**(%%) for distance measurement. DDS20-LB is of high accuracy to measure various liquid such as: (% style="color:blue" %)**toxic substances**(%%), (% style="color:blue" %)**strong acids**(%%), (% style="color:blue" %)**strong alkalis**(%%) and (% style="color:blue" %)**various pure liquids**(%%) in high-temperature and high-pressure airtight containers.
  The LoRa wireless technology used in DDS20-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.
