The Dragino DDS04-LS is a LoRaWAN 4-Channels Distance Sensor for the Internet of Things solution. It is capable of adding up to four Ultrasonic Sensors to measure four distances at the same time.
The DDS04-LS 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.
It detects the distance between the measured object and the sensor and uploads the value wirelessly to the oRaWAN IoT Server.
The LoRa wireless technology used in DDS04-LS allows the 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.
DDS04-LSsupports BLE configure and wireless OTA update which make users easy to use.
DDS04-LSis powered by a solar-powered + Li-ion battery, it is designed for long-term use for up to 5 years.
Each DDS04-LSis pre-loads with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server and it will auto-connect after power on.
