Fresh cut wood contains a lot of water. The humidity level is reduced to shipping dry level 18-19% during a wood dry process.
An extra dry process is used to the appropriate humidity level. Wood for the building industry contains 14-16% humidity level and when used for parquet floors to 8-10% humidity level.
The problem
Following the incorrect wood dry schedule results in dry faults, which impacts the wood during its processing and usage afterwards.
The challenge
To secure that during the wood storage the appropriate humidity levels are used to:
To avoid cracks and deformation
To avoid discoloration.
To avoid curved wood.
What to check
Humidity conditions during storage and the wood dry process need to be checked continuously.
Solution
Installing verification systems used to be very costly since much cabling was required. WiSensys uses wireless technology in combination with advanced measurement capabilities making real time monitoring of humidity possible in wood storage and wood dry places with a minimum of installation cost.
Wood storage customer
Below a wood storage customer who has several places to dry wood – depending on the wood dimensions and wood sort – and uses a combination of temperature and humidity measurements.
The base station and sensor positions are shown in the below figure. Storage Room 1 is used for parquet wood and uses a humidity probe in combination with the WS-DLXv.

Customer feedback
Before problems arise we are informed and can take preventive actions, saving cost.
We can demonstrate that the wood has been stored under the right conditions in our storage facility.
The WiSensys installation went very easy and quickly.
