Bee counter
Detection of honey bees in/out
Knowing bees activity could be studied by counting their out and in.
This is a try with some LDR that do not emit light that may possibly perturb bees. We firstly though about infrared sensors but we do not know yet if infrared can stimulate activity of bees. LDR should be enlighted by ambiance light and should not disturbs bees from light point.
