25 -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.
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 -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. 
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.

To be specific, the product emits modulation wave of near infrared ray on a periodic basis, which will be reflected after contacting object.
