Alternative to PIR sensor

[Oracle]

Hi all,

Does anyone know of an alternative motion sensor to a PIR (maybe Ultrasonic or Microwave)?

Basically a PIR is being set off by the steam/flue from a condensing boiler in the cold mornings.

I'm hoping there will be a solution that won't be susceptable

Thanks,

O.

I would go for a decent Dual/Tec which is ultrasonic and PIR

I don't suppose you would have a link for a suitable outdoor dualtech?

what is this pir controlling / triggering?

cheers mate are they rated for lighting?

Not without a relay, contacts (NC) rated at 100mA @ 24V

Operating voltage = 9-16Vdc

Looks like a good piece of kit though, I'm getting seriously hacked off with crap PIRs

They are really good, I've fitted a few of them now, with relays for lighting, and I've had no problems
