PIR for motion detection in the garden & notification

[bernardgreen]

Of course it a passion, why waste 50 years experience in designing electronics.

And it does exactly what is needed here with the capacity to be expanded.

Then crack on, Bernard, and maybe one day I will get to buy Bernard's reinvented wheel.

 

[bernardgreen]

Would you fit one of these



on one of these



The F1 wheel was a development of the wheel, not a re-invention.....

If it made the racing more interesting than it is now then hell yeah, let's do it.

So tell me what your DIY box of tricks does better and is more suited to a general application, or your application for that matter.

 

[bernardgreen]

It was designed to do what was necessary. No more , no less.

It is not suited to a general application, it was never intended for that.

It didn't answer the question though, Bernard, but I guess we'll leave it there and let the thread speak for itself.

Not having a go Bernard just there is an off the shelf option for somone with no electronics background !

I realise that

just there is an off the shelf option for somone with no electronics background !

but many of these are sold by the glitz and glamour of a "sexy" appearance.

The functionality as an alarm system takes second place to appearance.

The more glitz and glamour that is added to the alarm system the more there is to go wrong.

Customers want gimmicks and the marketing people will provide those gimmicks as sales incentives without always explaining to the customer the adverse effect those gimmicks can have on the necessary functions of the alarm system.

Utter defensive rubbish, Bernard. In this case you were wrong with your misinformation and now you're attempting to justify it by blaming manufacturers for doing what customers ask for. May I suggest you get hold of a Dygizone before commenting on it. Yes it is a smart little controller but then why shouldn't it be if it has to be placed around a home!

There are no gimmicks, it does exactly what it is required of a PIR/security light alarm. I'm actually still waiting for there to be a separate audio tone for the second PIR on one zone and then it'll be perfect for an off the shelf, relatively inexpensive, neat and tidy, easy to use, expandable, multi programmable system.

Good, you are happy with you choice, I am happy with mine. I fully understand mine and if I wanted different tones for different zones / PIR activations then I would spend a few minutes to add it. (*) I wouldn't have to wait until market led demad persuaded the manufacturers to add it as "standard" feature.

(*) to add a different tone for when an input activated would be about 40 extra lines of microprocessor coding if it was an existing cadence with a different frequency. 60 lines if I decided to create a new cadence as well.

I get that, Bernard, but again that isn't the issue. These threads are read by many people and advice is taken away. For someone claiming to be so knowledgeable you were wrong in the advice you gave to the OP. Your response was more about yourself than it was the point in question. Alternative methods are great to read but not at the expense of inaccuracy.
