I'm having an issue with armadillos digging up my landscaping. I tried a variety of different repellents but nothing seems to work. So now it's time to introduce a Nano. However, I'm not sure what sensor to build around.
My idea is to sense the armadillo's presence and make a rattling noise with a motor.
My experience with PIRs is they can generate false triggers during warm windy nights. I believe I would have to turn up the sensitivity to trigger on an armadillo so that would make things worse.
I'm reading that most ultrasonic sensors don't do well in an outside environment. The ones that do are expensive and may not pick up on my target. I can't determine if an IR or ToF sensors are better suited to be used outside.
Any insight on this is greatly appreciated. I'm getting tired of replanting my plants every morning. It's so dry here in Texas that some of the wildlife is coming out of the woods seeking moist soil to forage. They dig up my flower beds. I repair the damage and water the plants. It's becoming an endless cycle.
