The Dragino DS20L distance sensor stands out as a LoRaWAN sensor innovative LiDAR sensor that leverages LiDAR technology to deliver ultra-precise remote monitoring with a range of up to 2 m. Upon installation, integration into the LoRaWAN network, whether public or private , is completed in minutes without any technical complexity. Preconfigured with DevEUI, AppEUI and AppKey keys, this LiDAR sensor eliminates tedious configuration steps, making it a preferred choice for rapidly deploying IoT projects. Its compact and robust design is designed for easy installation, whether mounted on a fixed structure or embedded in a mobile measurement vehicle.
Designed to operate in demanding environments, the Dragino DS20L sensor maintains high accuracy even when faced with thermal and hygrometric constraints. It withstands extreme temperatures ranging from –40 °C to +80 °C as well as high humidity levels, making it ideal for predictive maintenance and level management of industrial silos or tanks. Distance and level readings are carried out without interruption, thanks to a waterproof and dust-resistant housing, ensuring optimal reliability whatever the external conditions. This robustness also allows it to be used for obstacle detection in urban environments or on critical installations, preserving the safety of infrastructure and personnel.
The onboard long-life battery provides several years of autonomy in standard use, minimizing maintenance costs and on-site interventions. In the event of a temporary network outage, the internal datalogging mode takes over by storing measurements locally, to transfer them automatically as soon as the LoRaWAN connection is restored. This dual capacity— active standby and buffer memory—optimizes data continuity, essential for applications where data loss can compromise analysis quality or security, such as in water level monitoring or barrier crossing detection.
The Dragino DS20L distance sensor offers several measurement modes to adapt to various needs: one-time measurement for static conditions, continuous measurement for real-time monitoring and alarm mode to trigger notifications as soon as a critical threshold is exceeded. It can also function as an event counter , useful for recording the number of passages or fillings, for example when a vehicle passes or a drum is filled. This versatility allows IoT engineers to configure the sensor precisely according to the requirements of each application, without having to change hardware.
Sensor configuration is easily done via a USB-C cable using AT commands, providing direct access to advanced settings without interrupting operation. For integrators working remotely, LoRaWAN downlinks allow for changes to transmission intervals, alarm thresholds, or measurement mode without having to travel to the site. This remote configuration flexibility is a major asset for large-scale deployments, where each optimization can generate significant savings in time and resources.
The long-range connectivity of the LoRaWAN protocol ensures extensive coverage, even in hard-to-reach areas or inside large industrial buildings. The Dragino DS20L distance sensor's low power consumption, combined with its extended battery life, ensures continuous monitoring without compromising battery life. Distance, level, or obstacle data are thus transmitted reliably and securely to the monitoring platform, where they can be analyzed to implement predictive maintenance, alert, or operational optimization strategies.
By choosing the Dragino DS20L distance sensor, companies equip themselves with a high-performance LoRaWAN LiDAR sensor , ready to meet the challenges of level management , obstacle detection and predictive maintenance in the most demanding environments. Its ease of installation, mechanical robustness, versatile measurement modes and long battery life make it a reference IoT solution for any connected sensor architecture. Thanks to Dragino's expertise in IoT connectivity products, users also benefit from quality technical support and regular software updates, ensuring the sustainability and security of their LoRaWAN network. With the DS20L distance sensor, remote monitoring reaches a new level of precision and reliability.
