PIR with long(ish) range?

HappyHippyDad · Feb 2, 2014

Hello all..

The customer wants his garden light to switch on the moment he walks into the garden, the sensor is around 12 meters away and it doesn't switch the light until he is half way up the garden. There is nowhere nearer I can locate the PIR.

I realise screwfix/toolstation have PIR's which state 12m but I know that they only work up to around 7-8m.

Does anyone know for sure which PIR's would be good for longer distances? I've found these External Security Lighting Products for Home

they look ok (very narrow spread though - 10degrees) but was hoping for some first hand experience from you chaps?

Thanks.

Usually if a PIR is sensitive to detect motion 12 m away then it's going to be too sensitive and false triggering will be a big problem.

You say there's nowhere closer to mount one but surely you could install a wooden post or even use the broken beam type sensors

I once fitted some microwave type PIR's that were designed for long corridors, not sure if they make Outdoor type though.

I found that the wickes floodlight and sensors are 1 of the best. Quite sensitive. Worth a try. I always use them.

for range, a narrow beam sensor will give more. typically about 25m against the 12m of a wide beam.

Have used the steinal ones that do 14 m. Not too cheap thou

Personally I like GJD opal pirs, been on market for years, good range 10-35m, and well priced around £45

Replaced some gjd sensors. Very good but pricey.

I've got spare gjd sensor brand new. I'm not gonna use it so if anyone needs one, give me an offer.

Thanks all, you've given me a few sites to look at, cheers

Second the Steinals.

OK chaps, I'd like to add to HHD's request.

I'm after an outdoor PIR or microwave sensor, 230V, not requiring a separate interface box, with a range of over 20m.

It's to control maybe 50 or 100W of LED floodlighting on the side of a church, and needs to spot someone walking up the path across the churchyard, so narrow beam angle will do fine.

Any thoughts (with a link if possible)?

Thanks

Look at the links already posted

As far as I can tell, the only links so far are to ELV sensors which require a separate control unit to actually do the switching. Surely there must be simple 230V AC stand-alone sensors that will do narrow angle, long range?

Hi Handy,

The steinel one mentioned states up to 14m and as its classed as good quality it may perhaps live up to this claim. The previous link I supplied did link to a 12v, however this link shows the 240v PIR long range.. expensive though and I cant find any reviews on it to make sure its ok, up to 35m's though!!

Yes, I guess that one fits the bill (if reliable), although it does look a bit 'cobbled together'. Not the neatest thing I've screwed to a wall!
