The Dragino DDS45-NB is a NB-IoT 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 ultrasonic sensing technology for distance measurement, and temperature compensation is performed internally to improve the reliability of data. The DDS45-NB 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 and send IoT platform via NB-IoT network.
DDS45-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.
DDS45-NB supports BLE configure and OTA update which make user easy to use.
DDS45-NB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
DDS45-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
