2. A surveyor finds dry rot in a roof void but can’t see how far it has spread into the room below. He can fit sensors and will get a yes there is dry rot until the point where the dry rot stops. Or he can map out the spread of moisture that will tell him the whole "at risk" area, then examine the sensors and establish how far the dry rot has spread within that at risk area. He has then established how far he has to go with his treatment in order to stop the dry rot from spreading further.

3. An area previously treated for dry rot becomes wet as a result of a flood from a pipe or similar. As the area dries out the sensors can be checked to ensure that there is no dry rot re-development . Once dry there is no longer a risk, the sensors can be removed.

4. An outbreak of dry rot has spread behind some ornamental panelling in a historic building. To treat the outbreak by conventional methods would involve damage to the panelling. Sensors can be fitted within and around the affected area and the activity of the fungus monitored. Environmental control principles can then be applied and the sensors used to monitor the dying back of the fungus as the control takes effect. The sensors may then be used as a regular or even permanent way of monitoring the area, all without damage to the historical artefacts.
