Can moisture damage be captured with weather data?

Can moisture damage be captured with weather data?

How we catch moisture in wood and wooden structures

The intelligent moisture meter is built around an algorithm that uses weather data on precipitation, humidity, air pressure, dew point, wind direction and speed to assess whether the amount of moisture in the wood is at a reasonable level.

In order to detect moisture and irregularities in the wood construction, we combine our data with DMI's Free Data. Through this combination of data and meteorological observations, which can affect moisture measurement in the tree, we are able to analyze ourselves to critical situations.

The measurements are made in real time and are sent to our platform. Here data is analyzed and if situations with critical conditions arise, the customer is notified.

The combination of the sensor's data and DMI's weather data makes it possible to find patterns that can detect inappropriateness. Here is sensor data together with information about precipitation and humidity from DMI's Free Data:

Interpolation of data

Through interpolation between data from surrounding measuring stations, we are able to find the best estimate of the actual weather situation at the sensor's location. The estimate of the local weather can be found through a weighted average of the values from nearby weather stations.

Interpolation helps us detect irregularities in time – a method more specifically called Invers Distance Weighting. This method makes it possible to respond to situations where moisture damage such as mold and rot can occur.

DMI's data is collected continuously through the use of serverless Cloud Feature on Google Cloud and stored in BigQuery.

Sensor solution can detect leaks and mold growth

The intelligent sensor solution can be used in several contexts, including detecting leaks, water damage, rot and incipient mold growth in buildings.

By placing the sensor in selected strategic locations in the building and analyzing the measured values together with weather data from DMI, you can capture and repair damage in wood and wooden structures before they occur.

Moisture meter is placed in exposed places in the building such as by:

·      Creepers

·      Floor separation

·      Twigs and scotsman

·      Facades of drainpipes

·      Penetrations (chimneys, ventilation systems)

One advantage of the intelligent sensor solution is that it can be placed in hard-to-reach constructions.
