DS20L
LoRaWAN Smart Distance Detector
The Dragino DS20L is a smart distance detector base on long-range wireless LoRaWAN technology. It uses LiDAR sensor to detect the distance between DS20L and object, then DS20L will send the distance data to the IoT Platform via LoRaWAN. DS20L can measure range between 3cm ~ 200cm. DS20L allows users to send data and reach extremely long ranges via LoRaWAN. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. It targets professional wireless sensor network applications such smart cities, building automation, and so on. DS20L has a built-in 2400mAh non-chargeable battery for long-term use up to several years*. Users can also power DS20L with an external power source for continuous measuring and distance alarm / counting purposes.

How it works
Remote airflow monitoring via LoRaWAN
Deploy AirFlow-LN at critical airflow points, transmit measurements through a LoRaWAN gateway, and use platform data to detect weak airflow, filter problems, or abnormal ventilation conditions earlier.
- AirFlow-LN measures airflow in ducts, refrigeration, or ventilation points.
- LoRaWAN gateway receives data from distributed sensors across the site.
- Cloud platform visualizes trends and helps trigger maintenance decisions.
