How to detect wild animal pests in a windy garden?

If these ultrasonic repellers actually work, then perhaps that would be the simplest solution.

Then no water would be needed, and I guess false positives would't matter.Anyone here have any experience with them or anything similar?
According to: http://www.lsu.edu/deafness/HearingRange.html
a raccoon can hear sound frequencies up to 40,000Hz! That's clearly way beyond the range of human hearing. -
They work well for dogs so don't use this if you have dogs in the neighborhood.
And where is the fun ? :PFor the tube it should work as long as it blocks IR from unwanted directions.

If you want to shrink the range of the pir sensor, just put some tape on the lens. About the repeller I tried once but it doesn't work on cats and indeed it was putting out a tone around 20khz but it wasn't bothering them besides drawing a little curiosity the first they heard it.

The trouble with these consumer devices is that it's very hard to know what it is that you're getting. No datasheets. Nonetheless, I'd say the minimum features are a frequency knob that encompasses a frequency range well outside human hearing (I don't want to be annoyed by hearing it), weatherproofing (preferably IP66 or better), a large mini solar panel (I've seen some with solar panels that seem just too small), and advertising on the box which claims that the device will rid the type of pest you want excised. That still leaves one vulnerable to being scammed, though, so I filter that list by picking the ones that have both the best reviews and a large number of reviews by verified purchasers.
On top of that, it probably means getting about three different ones made by different manufacturers so that hopefully at least one will actually do the business!
Wish there was an easier way.

So, I ended up ordering this one:
https://www.amazon.com/gp/product/B072LW4VWV/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
I'm a bit disappointed that it's only rated IP44 and not IP66 or better, but with luck it will be good enough as the near-term solution. The amazon reviews of it are encouraging that it will do the job. -
There are quite a number of products on the market which are advertised as pest "repellers," and literally all they do is blink an LED at a fixed interval all night long.
https://www.amazon.com/gp/product/B00KBAIGQO/ref=ox_sc_sfl_title_1?ie=UTF8&psc=1&smid=A1JF0FEJIRJQ6IThe funny thing is: their amazon.com ratings are almost as high as the ultrasonic device that I ordered. Makes me wonder whether any of this stuff actually works at all, or whether by the time people receive their orders the pests have moved on to greener pastures and so consumers wrongly conclude that their newly purchased repellers are effective.

Actually flashing light into eyes of a night mammal could indeed blind it temporarily as the eye takes time to go back to "low light" mode, not to mention being exposed to light may give off his position to any nearby predator. Anyway cats don't seem to be bothered but maybe something else is more susceptible to these kind of disturbances
-
I think a "sure fire" scare tactic would be to have an RC car race out and make a rukus near wherever animal activity is detected. If it could actually chase after the animal, then even better. It would require a whole different level of sophistication, but it's no longer pure science fiction either.

It might be time to level up :)

@gohan, @NeverDie - I just love the way this project evolves RC Cars and blinding leds... wonder where its going to end!
Oh, we've barely scratched the surface. That's why I'm hoping other people will add some ideas to the brainstorm. The more the merrier!
I kinda like the idea of having a jack-in-the-box fire off in the vicinity. That's sure to scare the bejeasus out of whatever critter wants to munch the plants. It would have to be able to re-arm itself automatically afterward though, because re-arming it manually would get tiresome in a hurry.

@NeverDie - How about something like a water pistol directly connected to a water hose? Maybe a bit to much water and a couple of false triggers and the plants will get enough water so survive a year... or drown.

That's almost the current situation with the motion activated sprinkler (see photo in OP). To the designer's credit, it's a very aggressive sprinkler, not one of the lazy, slow moving types we're all familiar with.

I oder the LIGHT IT by Fulcrum 20034-104 Motion Sensor Porch Light from https://stoppestinfo.com/372-best-raccoon-repellents.html .
I used it during one month and it work well, using the light like a repeller from raccoons. So i hear about one more way it is a water repeller, but still don't know how it work (i mean good or not))
Any suggestion? -

Scared the skunk away at least a couple times. The one I bought from aliexpress was total junk though.The water repeller thing may have helped. it's hard to know really.

@gohan do not judge anything by how it bothers cats. In my experience the only thing that bothers them is if you dont feed them or if you throw away their cardboard box.
The rc car would should work for most critters, really anything that makes a sudden motion should.
Side note raccoons are the only animal less bothered by people than cats.
