The battery
This FS21 main module houses a rechargeable battery that does not require user
maintenance.
In order to measure air humidity and to prevent pressure build-up in the casing, two
semi-permeable membranes are part of the casing.
For accurate air humidity measurements it is important to keep the humidity
sensor free of dirt and debris. Also make sure no water or dirt enters the
FS21 when the casing is open.
