Are these sensors going to be out in the open or reasonably protected (e.g., under an overhang)? If reasonably protected, they're cheap enough that I'd consider them for outdoor use--even if they fail, you didn't lose much, and I've used similar "indoor" sensors outdoors in similar conditions without problem (I can't make myself use the beloved Iris v2 mentioned above here, but my old Xiaomi, barely functional Kone, a Monoprice 15271, a Zooz ZSE18, and a well-protected Dome DMMS1 have all served or are currently serving in this function for me). I've seen some people suggest taping off the lens (so it doesn't get covered, then removing the tape afterwards) and spraying the sensor with silicone to protect it a bit if it's not protected when outside. That's what I did with my Konke (barely works on Hubitat as-is and also cheap so I didn't care), which isn't really protected aside from being attached to a fence and under the slight protection of a 1x4 or whatever is holding my fence together.
Otherwise, if you want something likely to last, I'd suggest one of the dedicated options above. But lots of people have used others outdoors with a bit of care (and possibly even without), so if you don't mind a potential loss, you could certainly try regardless. This is one I'd be willing to risk given the price. Your preferences, of course, may vary.
Plus, it's $35.
but the Version 3's work good for me. they are all protected from the weather.
