A brief note on dampness

Dampness in basements and sheds can lead to long-term damage, cause mold to grow, and also be an indication of flooding.

Note

The US CDC website at http://www.cdc.gov/mold/dampness_facts.htm recommends that humidity levels should be kept at about 50 percent in order to prevent molds from growing.

Therefore, it stands to reason that a high humidity level in a basement may be a sign of a problem. Thus, checking humidity levels will be a major factor in our damp and flooding detection device.

Let's get started with building the damp detection system.
