The Dragino LDS12-NB is a NB-IoT LiDAR ToF (Time of Flight) Distance Sensor for Internet of Things solution. It is capable to measure the distance to an object as close as 10 centimeters (+/- 5cm up to 6m) and as far as 12 meters (+/-1% starting at 6m)!. The LiDAR probe uses laser induction technology for distance measurement.

The LDS12-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.

It detects the distance between the measured object and the sensor, and uploads the value via wireless to NB-IoT IoT Server.

LDS12-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.

LDS12-NB supports BLE configure and OTA update which make user easy to use.

LDS12-NB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

LDS12-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
