I need to "sense" when a bird land on a perch. This will switch on a dc pump which will spray a fine water mist for a few seconds.
I've considered several ways...everything from having the bird break an infrared beam to having the perch tilt and make/break contacts from the birds weight. Also considered winding the perch with a coil which varies inductance when a bird lands on it.
Whatever I decide on needs to be able to stand up to weather and not false trigger excessively when light, humidity or other enviromental conditions vary.
Any suggestions? This is nothing more than a modern day version of a bird bath...just no water pool that will need refilling, get dirty or harbor mosquitos.
thanks!
