The Dragino LMDS200 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 LMDS200 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.

LMDS200 can measure two distances: the closest object and the next object behind the closest one.

LMDS200 supports the Alarm Feature, the user can set the LMDS200 to uplink data in a short interval when the distance is out of configured range.

The LoRa wireless technology used in LMDS200 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.

LMDS200 is powered by an 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

Each LMDS200 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.

Default FW in AS923, but it support US915, AU915 and all 900MHz Frequency by loading different FW, it could also support 868MHz if loading 868MHz FW, but there will be slight 0.5-1dB loss here.
