At the start of the project, we had a few challenges: Sub-zero temperatures caused vaulting of our sampling system, moisture caused electronics to misfunction, and environmental electromagnetic radiation interfered with our signal. Therefore, during the first months of the pilot, we updated W-MOD for an enhanced operation in factory conditions.

After the hardware modifications, we measured wood moisture with <1% standard deviation accuracy. Higher accuracy cannot be proven, because contemporary oven drying laboratory measurements have an accuracy of ≈1%.

Our measurements were not affected by changes in wood type, wood dust size, or frozen material. During the last months of our pilot, we measured moisture continuously with temperatures fluctuating between -20 and 30C.
