Cool! I assume this requires some soldering, etc, right? I wish I knew more about this kind of stuff. I’m guessing you’d probably want to hardwire the laser, too, right?
I’d really love to figure out a reliable driveway alert sensor of some sort. PIR tends to have too many false positives. Laser would be more reliable, I think, but would probably require a power source. (Not to mention that it would need to be weatherproof)
Fair point. For that matter, rain might do some crazy things, too.
A physical pressure wire might work, and seems like something that would be doable with battery power. I could probably disguise it in a groove in the concrete, but I don’t know if that’s even a thing.
BTW Most insects do not see light around the 650 nm (yellow) range there are retail lights called “Bug lights” that are yellow that people can see but bugs can’t.
My only suggestion, if you care to know, if not, oh well. Is to reduce the potential for false alarms by have two parallel beams of light with two different receivers far enough apart bugs and small rodents wouldn’t activate it and acting as one sensor. So one device to setup in the Wyze app.
If you really want to up-the-game, Super-Super-Super Geek style, so the sensor can not be fooled easily with another laser. Is lasers can transmit sound waves and the same type of receiver can understand the signal, You need to figure out the details, but it seem easy enough.
