I think you'll find people much more inclined to help you here if you make an effort to express your interests clearly. Writing in abbreviated text might make things quicker and easier for you, but it makes it harder for those who would help you to understand what you want.

Think of your requests from the perspective of the respondents: what's in it for them? If you make it an enjoyable and meaningful experience, you're likely to get a lot more help in return.

hi,
If your robot smoke/heat detector is at floor level, smoke and heat rise!.

In a closed room the floor level smoke detector would require the room to be full of smoke/heat...
IMO any 'alarm' would be far too late to do any good.

Thats why smoke/heat detectors should be mounted on the ceiling.

I support 'Hank' regarding text-speak aka sms-speak.

What about a cheap non-contact IR thermometer aimed straight up? That would detect heat incredibly well from the floor. Assuming nothing was in the way.

English is obviously not his first language.

Which is strange because you'd think he'd be less likely to use abbriviations, there again he's probably picked them up from a forum with a lot of lazy members.

I'd like to presume the best, too, but something doesn't seem to add up here. If he learnt English primarily from forum-speak, you'd have to presume he has a certain amount of familiarity with using the Internet. Yet despite the numerous suggestions on what he might Google (and even more specific links he could try), he refuses to do any work either in following-up on those leads or making a better attempt to articulate himself.
