Good motion sensor! IDEA: ext.PIR + fibaro universal/RGBW

[ivan.ruban 3]

I have following requirements to motion sensor:

1) Compact size

2) DC power

3) Non-expensive

Unfortunately there is no sensor from Fibaro (still waiting!!!). And the alternatives we have:

a) Everspring SP102 - big, ugly, battery powered that dies so fast.

b) Aeon multisensor - nice design, DC5V, but not fully supporterd by HC2. I also have long delays sometimes between motion and action - not good!

c) Can you recommend something else?

As another option I think also about a cheap external PIR sensor with fibaro module. Take a look for example at

- costs 9 bucks and is very small, runs on DC power, but has no box.

The mentioned above PIR sensor produces 3.3v as a logical TRUE on the output pin. If I connect it to analog (0-10v) input of Fibaro RGBW - that I guess (not tested) I can use it as a trigger for other Z-wave device. Is my understanding right?

I think also about connection of PIR to Fibaro universal sensor. Fibaro universal is much more compact than RGBW, and also cheaper. But I am not sure if 3.3v on a binary input of universal sensor can hurt the device. Is it OK to have voltage on a binary input of universal sensor?

I guess in order to use external PIR with universal sensor I need a 3v relay in the middle. Otherwise, the voltage on universal input will probably destroy it.

Guys, do you have any recommendations on a reliable zwave DC/mains powered sensor?

I use a 12v PIR at my front door with a potential free relay in it. It is designed to switch loads other then the 12V. So i combination with a universal module it works fine! I also connected my doorbel to it witch is running on 12V controlled by the universal module as well.

Mmmm .. strange. My AEON Multisensor react quickly. I don't have this kind of problem. But, more times pass with zwave ... and more i think that any installation differs from other ones.

As another option I think also about a cheap external PIR sensor with fibaro module.

I used this installation for Garden Light PIR in order to "re-use" the two old PIRs without buying new one.

In my system : any single PIR control a single relay. The relay control a single input of the 2x1,5Kw fibaro module.

In total : 2 PIR, 2 relay and 1 Fibaro module (Front Light / Back Light)

Bye

Thanks for idea candrea77! It is also a good and simple solution for external non-zwave PIRs.

This is a good solution in case if your external PIR has a built-in potential free relay. Works as a charm.

any single PIR control a single relay

This is also a good solution - in case if you need to control the load directly.

/emoticons/default_icon_wink.gif" alt=";-)" /> The advantage of menno26's solution though is - it can be configured as "motion sensor" in HC2 and thus is used as a part of security system (alarm panel).

In my case it is 3v on output PIR's pin in case of motion. It will work of course with 3v realy in the middle between PIR and Univ (or Fibaro Sw) - but it becomes a bit comlicated solution and also costs more.

So I connected PIR to RGBW which can read voltage changes. It works fine but there is the same problem as in PIR+Switch solution. The analogue sensor cannot be configured as motion sensor in RGBW. The available options for sensors in RGBW are only: light, temp, hum, other. So I cannot use it in alarm panel.

Exactly the same thing I described here,

I hope this option will be added in future releases...
