yuo claim that replacing triacs turns makes a dimmer go from a leading
edge to a trailing edge dimmer.

Only in your rather warped mind.

For someone who works in the education field not being able to learn

He's just taking the ****, Dave. He HAS to be, no way could he be THAT

Could he?


I hope not. But he is in education.


Not even that, can't bull**** its way out of a wet paper bag.

Most obviously currently with pet insensitive PIRs.


what are pet insensative PIRs do ou really think a pets infra red foot print is that difernt from a humans well it not.
All these so called PIRs do is lower the sensativity, if you set it to ignore 40KG animals it wontl detect 40KG of a child either.
You're just fooled by adversising.

Features vary by manufacturer and model, but can include selectable sensitivity for pets up to 40 pounds or those weighing up to 80 pounds and can be set to disregard one large pet, like a full-grown dog or several small pets, like cats.

It's just a sensativity setting or you angle them above floor level.

You really need more than just a PIR.
