1.1	19
39.6	20
70.4	21	The Dragino DDS75-LB is a (% style="color:blue" %) LoRaWAN Distance Detection Sensor(%%) for Internet of Things solution. It is used to measure the distance between the sensor and a flat object. The distance detection sensor is a module that uses (% style="color:blue" %) ultrasonic sensing technology(%%) for (% style="color:blue" %)distance measurement(%%), and (% style="color:blue" %) temperature compensation(%%) is performed internally to improve the reliability of data. The DDS75-LB can be applied to scenarios such as horizontal distance measurement, liquid level measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewer, bottom water level monitoring, etc.
1.1	22
70.4	23	It detects the distance(% style="color:blue" %) between the measured object and the sensor(%%), and uploads the value via wireless to LoRaWAN IoT Server.
1.1	24
67.3	25	The LoRa wireless technology used in SW3L-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.
1.1	26
67.3	27	SW3L-LB (% style="color:blue" %)supports BLE configure(%%) and (% style="color:blue" %)wireless OTA update(%%) which make user easy to use.
62.4	28
67.3	29	SW3L-LB is powered by (% style="color:blue" %)8500mAh Li-SOCI2 battery(%%), it is designed for long term use up to 5 years.
1.1	30
67.3	31	Each SW3L-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.
