**The Dragino LDDS04 is a LoRaWAN 4-Channels Distance Sensor for Internet of Things solution. It is capable to add up to four Ultrasonic Sensors to measure four distances at the same time.

**The LDDS04 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.

**It detects the distance between the measured object and the sensor, and uploads the value via wireless to LoRaWAN IoT Server.

**The LoRa wireless technology used in LDDS04 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.

*LDDS04 is powered by 8500 mA Li-SOCI2 battery; It is designed for long term use up to 10 years.

**Each LDDS04 pre-loads with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect if there is network coverage, after power on.
