CROW D&D should do, but i suggest that you listen some other opinions as well, which i bet will appear soon..

Could do with knowing where and why you are installing it.

Due to the fact that PIR's work on the principle of detecting moving heat, I would assume that all PIR's will false alarm if steam was present.

Can you use IR beams or sonic detectors? Or even a Dualtech, but I wouldn't like to say how ammune it would be either?!

Electrically there is no reason for not using any 12vdc PIR in a bathroom. Enviromentaly influences is your only issue. A normal PIR would perform quite well in my own bathroom as i don't have issues with steamy wet enviroments. use your discression on siting.

I dont understand how there is likely to be steam in your bathroom when the alarm is set, surely that would mean the room would be occupied?

More to the point, i would suggest installing a detector in a bathroom is going to be a waste of money as it will have corrosion on the pcb in a matter of weeks if not days.

If you really must put a sensor in your bathroom (which i doubt you really need to) then an external sensor would be best ( i think a redwall will look brill and you can be sure no one else will have one ).

My best suggestion would be to contact the door or put a sensor outside the bathroom door, but certainly not inside.

CROW D&D is IP54. Planned for outdoor use.

According to new EN-norms it should be environmental grade/class 3 or 4 detector.

I agree, unless the device is waterproof, it will corrode

I'm assuming 'bathroom' and 'shower' were meant as examples

( i think a redwall will look brill and you can be sure no one else will have one ).

and like i said before CROW D&D is suitable for outdoor installation. Of course it is not waterproof in sense that you could sink it in the water.

Price is (in Finland) approximately 5x normal PIR thou..
