RE: Sat on a Toilet Sensor ?

["Marcus Warrington" <marcus.warrington@xxxxxxxxxx>]

.. what happens with the loo seat is closed and the PIR detects
someone
in the room.



Also the idea of mounting electronics in the bowl itself just seems
wrong to me.. especially in a country where I can't even have a light
switch in the bathroom itself.

I've had another thought...how about a light sensor detecting light
inside the bowl. If the bowl is "dark" start fan. You'll probably
need
an additional method to condition the output so that the fan doesn't
just come on at night (e.g. PIR in bathroom, contact from a relay in
the lighting circuit etc.)

The light sensor could be small enough to mount under the rim, and you
could also "pot" the electronics to make the thing a bit more
hygenic.

Any use?

Cheers,

Tim.
