DisDro by EVALAN
Connected Rain Sensor
An acoustic rain meter with rhythm.
The Disdro Sensor is a smart device with data processing capabilities and real-time communication that provides continuous and detailed information about precipitation at high spatial resolution in real time.
Through a drum, the Disdro Sensor “listens” to the rain and transforms the vibrations into electric energy to then calculate the size of the drop, the distribution, the volume of water and the linear units of rainfall.
The Disdro Sensor’s high sensitivity allows it to provide precise readings even in instances of low rainfall, excelling in heavy rainfall conditions where other rain gauges may falter. Additionally, it can differentiate between rain and hail providing accurate measurements for both.
We are dedicated to helping our customers achieve the best results.

In partnershop with NACO
EVALAN is currently working in partnership with NACO (Netherlands Airports Consultants) to implement an innovative IoT infrastructure that enables real-time airport runway monitoring with the Disdro Sensor.
NACO aims to streamline the mandatory process of runway condition assessment and reporting for airport operators in the aviation sector by providing a real-time and continuous monitoring service through this innovative solution, which includes monitoring of runway wetness and water levels that would otherwise require manual checks.
Key benefits include
- Affordable, accurate and reliable.
- Highly sensitive to both low and heavy rainfall.
- Accurate in measuring and differentiating between rain and hail.
- Robust and low maintenance.
- Easy to install.
- Connected to the cloud
