Can Cytech make micro sensors

[admin]

Will there be a problem due to the angle of coverage being very narrow? You would need to be directly under it to be detected

[Swiss-Toni]

The angle of the beam is only determined by the depth of the pir in the housing and this is easily adjusted just push it to the depth required. The overall idea of this was to reduce the dispersion field to stop activations unnecessarily. These sensors are more in tune with walking past rather than walking under (for my purposes) to use as a walk under the dome of the sensor would be adjusted fully out giving a wide dispersion field.

Using the output of the module to drive a mini relay with NC contacts would mean you can use the zone inputs like normal.

It does not require a relay to drive comfort , comfort just has to be programmed as digital on that particular sensor/zone and it works as it should, it just didn\'t work under normal PIR parameters N/O or N/C. That seems to be the requirement of the module their is no need for any further relays etc in fact the power requirement could also be taken direct from comfort considering it only uses (12V) <60uA
The point I was trying to make is that it maybe an idea that Comfort should take up and manufacture as I see a potential for this in the market place for home automation & security systems.

We would need to find a better source of the miniature PIRs. The parts from eBay may not be a long term source.
Do others find this product useful for Comfort?

[Swiss-Toni]

Not sure who manufactures them I only bought them as I could not buy what I required and adapted to suit the installation i really don\'t have any idea where else to get this sort of equipment from, its not the most cost effective method for me to make these as I\'m sure it could be done a lot better by a company like Cytech.
It may be a an idea to do poll and see if it would be popular or if their would be a demand for it.
The size element and installation make it unique at the present time as I have been unable to find anything like it. Also the advantage of where it can be situated and what it is used for make an ideal tool for various applications.
I will try to refine the design a bit more making it smaller and with a slightly different edged finish depending on the availability of different parts for the design also after looking at what has been said I think there should be two types wide and narrow dispersion field. (looking at getting it down to 14mm from 16mm)

They look nice, the challenge though is being able to get wiring/power to them I guess.

Hi Julian

You have made me look at an area regarding wiring (so far it has not been a problem for me) but if they are fitted into a wall, plaster on brick there certainly would be an issue with fitting. (I am going to do this on an external wall to try it out in the near future, if you want I will let you know how this goes)
However I have so far fitted only to staircase and a ceiling and they fit snugly and wiring is very basic. I would have to say that they would only be suitable for drywall and timber. If you think about it with this design you can place them in the ceiling above window rather than wall mounted (just an idea)
The wiring is almost the same as any basic PIR + - & trigger, the connection is standard Dupont crimps on the sensor terminal and i used cat cable for the run.
