Right...back on a laptop - I purchased the item linked below. Amazon should have similar for a couple bucks more.

Integration part was easily...bit of hackey python does the trick.

Noted very slight buzzing sound which was irritating if next to bedstand. Not a major concern.

Don’t recall. Nova something. Like 15 bucks off amazon. Looking at the pictures they all seem to be same thing rebranded.

Measures 2.5 and 10. Def works ie reacts to window being opened but I wouldn’t stake my life on accuracy

Good for a project though
