DDS45-LS solar-powered LoRaWAN ultrasonic distance detection sensor

The Dragino DDS45-LS is a  LoRaWAN Distance Detection Sensor for the Internet of Things solution. It measures the distance between the sensor and a flat object. The distance detection sensor is a module that uses ultrasonic sensing technology for distance measurement, and temperature compensation is performed internally to improve data reliability.

The DDS45-LS 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 wirelessly to the LoRaWAN IoT Server.

The LoRa wireless technology used in DDS45-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.

DDS45-LS supports BLE configure and wireless OTA update which make users easy to use.

DDS45-LS is powered solar + Li-ion battery, it is designed for long-term use up to 5 years.

Each DDS45-LS is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server and it will auto-connect after powering on.
