AVR-Chat

Im looking for an intelligent module that sends some sort of signal to an MCU. The module should be able to negotiate a vehicle environment of changing temp., changing light, etc yet able to recognize persons at some significant accuracy.

so i guess photosensors are not an option

To "recognize" people may be a bit difficult. If you just want to
count the people entering a bus door, typically you use an
photoelectric sensror (for door/gate/elevator use). They
are very easy to be interfaced with any MCU, including
an AVR.

More established vendors:
Pepperl+Fuchs, SICK, Omron, SUNX, Banner Engineering
and many others.
