Urban microclimate observatory

If you are here because you scanned a QR code on a mysterious object, you have stumbled upon one or more microclimate sensors of the Helsinki Microclimate Observatory (HELMO) project. These devices track the temperature in their surroundings at 15-minute intervals. The mushroom cap, if present, shields the sensors from direct sunlight exposure.
Why is this sensor here?

The device you found belongs to the Helsinki Microclimate Observatory (HELMO), a large network of microclimate sensors maintained by the University of Helsinki's terrestrial ecosystem dynamics research group (Tree-D lab).

Data gathered by the Helsinki Microclimate Observatory will improve our understanding of urban forest climates. We hope that our results will help the City of Helsinki protect critical plant and wildlife habitats.

Sensor locations were chosen based on elevation, vegetation cover, and many other criteria. You can explore the approximate locations of our sensors on our interactive map, or find more information about the project on its website (currently only available in English).
Which sensor did I find?
What should I do now?

Please, take a step back (make sure not to bump the sensor or its protective cage if it has one), then feel free to continue your walk and enjoy your day! We kindly ask that you do not touch or move the sensor, as it could mess with our data. 

Got questions? Noticed the sensor looking out of place? Contact us at microclimate.hel@gmail.com. Feel free to visit our project's website, if you are curious to learn more.

If you, your children, or your pets accidentally moved the sensor, please notify us of the time of the incident at microclimate.hel@gmail.com.
