Outdoor PIR sensor buying guide

Updated: 20.10.2026

You have decided the path, the drive, or the porch needs a sensor, and the amazon.co.uk list has already mixed three different products into one scroll. This outdoor PIR sensor buying guide is the order to use before a brand: name the job, match the weather rating to the wall you actually have, then read the load or the hub. Shelf prices in our [motion sensor outdoor comparison](/hub/burglar-protection/motion-sensor-outdoor) ran from £10.96 to £79.99 on 19 October 2026. Peter F. used those listings and public UK guidance, not a lab test. A purchase through our links can earn a commission.

Three jobs, one shelf

A mains wall PIR switches a lamp you already have. It is silent, and it does not join a Hue scene. In this set that job is the Maclean and the three SEBSON wall sensors, roughly £11 to £18, all of them 3-wire boxes with a lux dial and a timer. The electrician, if you need one, often costs more than the sensor. A driveway kit chimes a receiver indoors. It does not light the path. If that is the job, leave this page for the wireless driveway alarm guide before you compare wattages you will never use. A smart battery sensor runs lights that are already on that system. Hue needs a Hue Bridge, sold separately, and only automates Hue lamps. Eve Motion needs a Thread border router. If you are stuck between a £12 wall PIR and one of those hubs, the wired PIR vs smart outdoor motion sensor page holds that fork.

Weather rating for the wall you actually have

IP65, on the Maclean, the dual-head SEBSON, the IR_OUT_IA, and the Betterlink heads, is the rating where rain hits the face. IP44 on the anthracite SEBSON at £13.99 is splash protection, so it is the porch unit, not the gable unit. IP54 on Hue is dust and splash. IPX3 on Eve is spray only. KERUI prints "IPV4", which is not an IEC code. Do not rewrite it as IP44. Believe the code that matches the wall.

Load, lux and the 12 m claim

If the sensor switches a lamp, read the LED watts, not the incandescent watts. The IP44 SEBSON allows 400 W LED. The dual-head allows 600 W LED. The IR_OUT_IA allows 1,000 W LED. The Maclean confirms 1,200 W resistive and never states an LED cap. Do not invent one. Three-wire means a neutral as well as live and switched live. That is not a reason to open the rose yourself. Lux runs from about 3 lux to 2,000 lux, and timers run to 15 minutes, except the dual-head, which stops at 7. A 12 m claim is a catalogue maximum.

What the price does not include

A £10.96 mains PIR can still be the dearest job once a registered electrician is booked. Electrical Safety First expects outdoor lighting to be installed to BS 7671. In England, Part P treats a new circuit as notifiable, while an extra lighting point on an existing circuit, away from a bath or shower, is not. Scotland and Northern Ireland do not copy that England note. A £43.99 Hue sensor is incomplete without a Bridge and Hue lamps. Signify's shop lists the sensor at £54.99. Eve at £44.95 is incomplete without a Thread border router. Batteries are missing from the KERUI box. Named picks, once the job is clear, sit on the best outdoor motion sensor page.

Common questions

What should I check before I buy an outdoor motion sensor?
Check the job first: lamp, chime, or smart scene. Then match the IP code to the wall, and only then read LED watts or the hub you still have to buy. A 12 m line and a half-mile line are not the same kind of range. Prices in this set on 19 October 2026 ran from £10.96 to £79.99.
Is IP44 enough outside?
IP44 is splash protection. It can suit a porch or soffit that keeps rain off the face. It is the wrong code for an open gable. In this set the IP44 SEBSON is the one reviews mention in the rain, despite 6,428 ratings at 4.2. IP65 is the listing mark for rain on the housing.
Why is the LED wattage lower than the halogen wattage?
The listings state a lower figure for LED or energy-saving lamps than for incandescent lamps, because the sensor's switch is rated differently for each. The IP44 SEBSON is 400 W LED and 800 W incandescent. Use the LED line for LED lamps. The Maclean page never states an LED cap at all.
What does 3-wire mean for a PIR?
On these mains listings it means a sensor that expects a neutral as well as the live conductors, so it can switch LED lamps without leaving them glowing. It is not a description of a battery chime or of a Hue sensor. A qualified electrician should make that connection. Do not treat the phrase as a wiring diagram.
Is 12 m the range I will get beside the house?
It is the catalogue maximum on several of these PIRs, not a promise for your path. Crossing the beams works better than walking straight at the lens. Some dual-head reviewers report about 4–6 m. That report is not a lab test, and it does not automatically apply to every other 12 m title.
Do I need a hub?
Only for the smart sensors. Hue needs a Hue Bridge, sold separately. Eve needs a Thread border router. The four mains PIRs and the two driveway kits in this set do not join those systems. A hub you do not own is part of the price, not an optional app.
When do I need an electrician rather than a better sensor?
When the work is a new cable or consumer unit, when you cannot identify the conductors, or when the outside circuit trips or looks damaged. Battery chimes, and Hue or Eve on a screw, are householder jobs if you follow the manual. A different sensor does not make a damaged 230 V circuit safe.
