Yea they’re just analog… They are designed to extend the reed switch beyond the actual device (that is actually how I track my doorbell being pressed).
I just wanted to put in a suggestion for someone that just wants a simple sensor that works pretty well but you have little control otherwise.
For what it’s worth, these work great for my setup and I haven’t had a single false trigger. However if I had a dog or cat, I’d want the force threshold the account for weight.
