When burning wood, it is important to know the wood moisture content. If the wood moisture content is too high during combustion, the water must first be heated and evaporated. This results in lower flame temperatures and smoldering gases. In addition, it can lead to incomplete combustion of the wood. In summary, too high a wood moisture content results in poor efficiency, pollutants and also odor emissions.

With the Bluetooth humidity detector, up to 44 different types of wood can be checked for their moisture content. These include 36 hardwoods and 8 conifers, such as beech, spruce, pine and maple. The measured value can be up to 150% moisture in relation to the dry matter. In order to obtain the most precise measurement possible, the Bluetooth humidity detector has both automatic and manual temperature compensation between -20 ... 50°C / -4 ... 122°F. In order to carry out a measurement, a pair of measuring tips is first knocked into the wood with the help of the ram electrode on the Bluetooth humidity detector. Two different pairs of measuring tips are available for the Bluetooth humidity detector. With the pair of needles 45 x Ø3.05 mm, you can drive into the wood up to a depth of 30 mm.

Then the type of wood to be measured is selected via an Android or iOS device and the measurement is started. The current measured value is displayed after a few seconds. The connection between the Bluetooth humidity detector and the mobile device is made via a Bluetooth 4.0 interface. After a measurement, the measured value from the Bluetooth humidity detector can be saved on the mobile device. The data can be exported in CSV and PDF format. A 9V DC power supply unit is used for the supply voltage of the Bluetooth humidity measuring device. For mobile use, the Bluetooth humidity detector can be operated with a 9V block battery.
