LS-MDD LoRaWAN Microwave Radar Distance Detection Sensor

Solution Overview

The s5system LS-MDD is a LoRaWAN Microwave Radar distance sensor. It uses 24Ghz Microwave to detect the distance between the sensor and different objects. Compare vs the ultrasonic or Lidar measurement method, Microwave Radar is more reliable for condensation / dusty environments. It can sense the correct distance even there is water or thick dust on top of the sensor.

The LS-MDD 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.

LS-MDD can measure two distances: the closest object and the next object behind the closest one.

LS-MDD supports the Alarm Feature, the user can set the LS-MDD to uplink data in a short interval when the distance is out of configured range.

The LoRa wireless technology used in LS-MDD allows devices 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.

LS-MDD is powered by an 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

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