The Dragino MDS120-NB is an NB-IoT Microwave Radar Distance Sensor for the Internet of Things solution. It uses use Microwave Radar to detect the distance between the sensor and different objects. Different from ultrasonic or Lidar measurement. Microwave Radar is more reliable for condensation / dusty environments. It can sense the correct distance even if water or dust is on top of the sensor.
The MDS120-NB 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.
MDS120-NB supports uplink methods including MQTT, MQTTs, UDP & TCP for different application requirements, and uplinks to various IoT Servers.
MDS120-NB supports BLE configure and OTA update which make users easy to use.
MDS120-NB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
MDS120-NB has an optional built-in SIM card and default IoT server connection version. Which makes it work with a simple configuration.
