What LoRaWAN distance sensors are available in the product range?

Ultrasonic Distance Sensors (DDS Series)

The Dragino DDS45 and DDS75 models are ultrasonic distance sensors with LoRaWAN transmission. They measure distances non-contact and are suitable for applications such as level monitoring, object detection, and distance measurement at medium ranges. The DDS04, as a 4-channel variant, simultaneously captures up to four measurement points. Battery-powered (LB) and solar-powered (LS) variants are available.

LiDAR ToF distance sensors (LDS series)

The LDS series uses LiDAR Time-of-Flight technology for high-precision distance measurements. The LDS12, LDS25, and LDS40 models differ primarily in their measurement range and features. The LDS25 also features an Auto-Clean function that automatically cleans the lens—perfect for dusty or humid outdoor environments. Battery- and solar-powered versions are also available here.

Radar Distance Sensors (MDS Series)

The MDS120 and MDS200 models are microwave radar distance sensors with LoRaWAN. Radar sensors operate independently of lighting conditions, dust, fog, or rain—making them particularly robust for challenging outdoor conditions. Suitable for level measurement, water level measurement, and industrial distance monitoring.

Smart Distance Detector (DS20L)

The Dragino DS20L is a compact LoRaWAN distance sensor that is easy to set up and ideal for simple detection and monitoring tasks. Use it, for example, for presence detection or as a trigger for automated processes.

Typical Applications for Distance Sensors

Level Monitoring

Ultrasonic and radar distance sensors are ideal for non-contact level measurement in tanks, containers, and silos. They transmit measurement data wirelessly via LoRaWAN, even over long distances.

Water level monitoring

Radar distance sensors from the MDS series reliably measure water levels in rivers, canals, and retention basins. They operate reliably even in rain, fog, and changing light conditions.

Object Recognition & Presence Detection

The DS20L is a compact LoRaWAN distance sensor suitable for detecting objects or people, for example, to control automated processes or as intrusion protection in outdoor areas.

Industrial Distance Measurement

LiDAR sensors in the LDS series provide precise distance measurements for demanding industrial and infrastructure applications—including those where a laser distance sensor is used with Arduino or other microcontrollers.

FAQ – Frequently Asked Questions About LoRaWAN Distance Sensors

What is the difference between a distance sensor and a proximity sensor?

Both terms are used interchangeably and describe sensors that measure the distance to an object. In practice, “distance sensor” is more commonly used in industrial and IoT contexts, while “proximity sensor” is also common in the automotive sector and for short-range applications. The Dragino sensors in this category are designed for medium to long ranges.

How far can LoRaWAN distance sensors transmit data?

The measurement data is transmitted via LoRaWAN—typically several kilometers in open terrain, and significantly further under optimal conditions. This means that even large open areas can be covered with a single gateway.

What is the difference between ultrasonic, LiDAR, and radar distance sensors?

Ultrasonic distance sensors emit sound waves and measure the transit time of the reflected signal—a proven and cost-effective method. LiDAR sensors use laser light and offer higher precision. Radar distance sensors use microwaves and are particularly resistant to weather conditions such as rain, fog, and dust—ideal for demanding outdoor applications.

What does the Auto-Clean feature on the LDS25 do?

The LDS25 features a built-in cleaning mechanism that automatically removes dust and debris from the sensor lens. This significantly extends maintenance intervals and makes the sensor particularly suitable for continuous outdoor use.

Are the sensors compatible with Arduino?

The Dragino LoRaWAN distance sensors are standalone units with an integrated LoRaWAN radio module and are not controlled directly via Arduino. If you are looking for a laser distance sensor for Arduino projects, you can find corresponding LiDAR modules in other categories at EXP-Tech.

Which distance sensor do you recommend for outdoor use in harsh weather conditions?

The MDS series radar distance sensors are ideally suited for rain, fog, and dust. Alternatively, LiDAR sensors with an auto-clean function (LDS25) offer a good solution when high measurement accuracy is required.
