Dragino LDS40-LB – LoRaWAN LiDAR ToF Distance Sensor (40 m Range, 8500 mAh Battery)

Dragino LDS40-LB – High-Precision LoRaWAN LiDAR ToF Distance Sensor for Long-Term IoT Deployments

The Dragino LDS40-LB is a compact, energy-efficient LiDAR Time-of-Flight (ToF) sensor designed for IoT applications that require accurate distance measurements in harsh or remote environments. Using advanced laser-based LiDAR technology, it can measure distances from 0.1 to 40 meters with centimeter-level resolution and high reliability—even under strong ambient light.

With LoRaWAN® connectivity, the LDS40-LB wirelessly transmits data to your IoT server or platform. Powered by a built-in 8500 mAh Li-SOCI2 battery, the device supports up to 5 years of maintenance-free operation, depending on configuration.

Ideal use cases include:

Horizontal distance or liquid level monitoring

Smart parking systems

Object presence and proximity detection

Robotic obstacle avoidance

Intelligent trash bin monitoring

Sewer and groundwater level detection

Industrial automation and control

The sensor supports BLE (Bluetooth Low Energy) for quick configuration and OTA (over-the-air) firmware updates, making setup and maintenance simple. Each unit comes pre-configured with unique LoRaWAN keys, allowing for quick deployment—just register and power on to connect.
