Basement Ventilation System (2)
In the companion installment we describe a control unit for managing the humidity level in a basement or other damp space with a ventilation system. The relative humidity and temperature indoors and outdoors are measured using ChipCap2 sensors.

Download the BOM list
The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
