Local lidar sensor with automatic range clearing LoRaWAN Dragino LDS25-LB/LS

The Dragino LDS25-LB/LS is a LiDAR ToF (time of flight) distance sensor with automatic cleaning for an IoT solution. It is able to measure the distance to objects at a distance of 0 to 25 meters. The LiDAR sensor uses laser induction technology to measure distance.

It has built-in a unique dust removal brush design, and the radar controls the dust removal brush to complete the optical mirror dust removal operation, and the user can customize the dust removal configuration.

The Dragino LDS25-LB/LS can be used in scenarios such as horizontal distance measurement, ore material monitoring, object proximity and presence detection, industrial material monitoring, forage crop monitoring, automatic control, etc.

It determines the distance between the measured object and the sensor and uploads the value via a wireless connection to the LoRaWAN server.

It supports BLE configuration and wireless OTA update, making it easy to use.

Dragino LDS25-LB/LS is powered by a Li-SOCI2 8500mAh battery or by a solar battery + lithium-ion battery, it is designed for long-term use of up to several years.
