been designing this CRITTER RIDDER for awhile now and didn't dawn on me that the PIR will not work in daylight.
By adding a photo transistor to take pin 9 HIGH (18F1320 PIC) durring daylight so the PIR is disabled.
my concern is battery life and is there a better solution?
Going to program the PIC w/ a timer to trigger the unit every 20 minutes but any suggestions on taking pin 9 LOW brifly durring the day.
thought about a diode after the photo transistor? to act as a gate??
