Motion sensor or presence sensor: what’s the difference?

Before buying, you need to understand the technical distinction that changes everything in daily use. A classic motion sensor uses a passive infrared (PIR) detector: it reacts to a heat source moving across its field of view. It is reliable, power-efficient (2-year battery) and perfect for triggering a light or an alarm when someone passes by. But it does not detect a person sitting still: read a book on the sofa and the light switches off.

A modern presence sensor uses a millimetre-wave radar (mmWave, 60 GHz) that detects micro-movements — breathing, heartbeat — and can tell a static presence apart from a draught or a moving curtain. This is the technology inside the Aqara FP2 or FP1E: the light stays on as long as you are in the room, even completely still.

Why install a smart motion sensor in 2026?

Security first: a perimeter that reacts

Combined with a subscription-free smart home alarm system, a motion sensor covers the rooms where a door/window sensor cannot see anything: once a door is forced, movement in the hallway triggers the siren and the notification in under a second. It is the natural complement to perimeter sensors: the latter watch the entry points, the former watches the inside. Since most burglaries happen through a door or window (European insurer data), the opening + motion + siren combination reproduces the essentials of an installed system for under €200.

Smart lighting, the first real use case

Light triggering is the #1 use of a motion sensor: entrance, hallway, staircase, garage, utility room. Combined with smart light bulbs or smart outdoor lighting, it turns the light on as you pass and off after you leave: no more fumbling for switches in the dark, plus measurable savings (an LED bulb left on needlessly 3 hours a night consumes about 8 kWh/year — twice its own running cost). Sensors with a built-in lux meter (Hue, Eve, Aqara) only activate when the ambient light is insufficient anyway.

Comfort and energy automations

The mmWave presence sensor transforms the home: the office light stays on while you work, the heating rises when the room is occupied, the AC switches off when you leave. Combined with a smart thermostat, it is one of the most profitable automations: the French environment agency ADEME estimates that an unoccupied room heated needlessly represents 5–10% of a home’s heating consumption. A €35 sensor paired with a thermostat can therefore pay for itself in one heating season.

How we tested the motion sensors

Our campaign ran from July to August 2026 (6 weeks) in two test homes: a 65 m² flat (hallway, entrance, office, bathroom) and a 110 m² house (entrance, living room, staircase, garage, utility room). Each sensor was installed at the same reference location and scored on the same grid, out of 10:

• Detection reliability — reaction time, false alerts (pets, curtains, heating), static presence detection.
• Range and angle — real distance, field-of-view width, behaviour in a hallway vs a living room.
• Battery life — real consumption, battery used, estimated lifetime.
• Interoperability — Matter, HomeKit, Alexa, Google Home, Home Assistant; hub required or not.
• Settings — sensitivity, off-delay, lux meter, detection zones, day/night mode.
• Installation and design — included mount, fixing, discretion, build quality.

Detailed comparison: the 7 best motion sensors 2026

1. Aqara FP2 — best overall (mmWave presence sensor)

The FP2 is the most accomplished presence sensor on the market: its 60 GHz radar detects up to 5 independent zones in a room, distinguishes static presence from movement, and can even ignore zones you mark as “unmonitored” (bed, sofa). It runs over Zigbee (Aqara hub required) with excellent Home Assistant integration, and its app offers very fine settings: sensitivity, off-delay from 10 seconds to 30 minutes, pet detection.

Best for: living rooms and offices where static presence matters. Score: 9.3/10.

2. Philips Hue Motion Sensor — best for lighting

The Hue sensor is the reference for lighting: it combines PIR with a lux meter, is configured directly in the Hue app (sensitivity, off-delay, time range) and triggers light scenes — not just a light, but a whole ambience. It works with the Hue Bridge (Zigbee) and pairs perfectly with the ecosystem’s bulbs and switches. Its advertised 2-year battery life (CR2450) checked out at 22 months in our test.

Best for: homes already equipped with Philips Hue. Score: 8.7/10.

3. Eve Motion — best for Apple (Matter over Thread)

The Eve Motion is a Matter over Thread PIR sensor: no proprietary hub, it connects directly to Apple Home, Alexa or Google via a Thread border router (Apple TV, HomePod, Echo, Nest Hub). It is the easiest of our comparison to install (2 minutes), with a built-in lux meter, adjustable off-delay and premium build. Its detection angle (80°) and range (9 m) sit in the upper average, and its CR2450 battery lasts over 2 years.

Best for: Apple/HomeKit homes and anyone who wants Matter without a hub. Score: 8.5/10.

4. Bosch Smart Home Motion Detector — best for an alarm

The Bosch detector integrates with the Bosch Smart Home Controller alarm system, one of the most reliable on the European market. Its detection was the most stable in our test: zero false alerts in 6 weeks, even with a dog in the house. It also measures ambient temperature and brightness, and can drive scenarios from the Bosch Smart Home app. Its weaknesses: a closed ecosystem (no Matter, no official Home Assistant support) and a premium price.

Best for: homes that want a real certified alarm. Score: 8.4/10.

5. Aqara Motion Sensor P2 — best Matter value

The Aqara P2 is a Matter over Thread PIR sensor at €35: it offers the essentials — sub-500 ms detection, lux meter, adjustable off-delay — in a tiny 3 cm format that mounts with adhesive or a magnetic base. It connects to Apple Home, Google Home, Alexa or Home Assistant with no proprietary hub. Its advertised 2-year battery life (CR2032) is realistic under normal use. The only real miss: no static presence detection.

Best for: outfitting a whole home in Matter without breaking the bank. Score: 8.3/10.

6. Shelly Motion 2 — best for tinkerers

The Shelly Motion 2 is the only direct Wi-Fi sensor in our selection: no hub, no border router, a complete local API and open-source firmware. Tinkerers love it (native Home Assistant integration, MQTT, webhooks), and it packs PIR, lux meter, temperature, humidity and even an accelerometer. Its battery life is shorter (6–12 months depending on use, CR123A), and it must be installed away from heat sources to avoid false alerts.

Best for: Home Assistant users and DIYers. Score: 8.0/10.

7. SwitchBot Motion Sensor — best budget

At €15, the SwitchBot sensor does the job: reliable PIR detection (7 m, 100°), lux meter, day/night mode, and Alexa and Google compatibility via the SwitchBot Hub (sold separately, ~€40 — factor that in). Without the hub, it only works with the SwitchBot app over Bluetooth. Its 2-year battery life (CR2450) and adhesive mount make it an excellent first sensor for trying home automation risk-free.

Best for: getting started with home automation on a small budget. Score: 7.6/10.

Selection criteria: how to choose your motion sensor

Technology: PIR or mmWave?

Simple rule: PIR to detect movement (hallway, entrance, staircase, garage), mmWave to detect static presence (living room, office, bathroom). PIR is cheaper, lasts longer on battery and covers 80% of use cases; mmWave is more precise but consumes more (mains or large battery) and costs 2–3 times more.

Ecosystem and protocol: Matter, Zigbee, Wi-Fi?

Check compatibility with your setup before anything else: an Aqara Zigbee sensor needs an Aqara hub, a Thread sensor needs a border router, a Wi-Fi sensor needs nothing. If you are starting from scratch, favour Matter (compatible with Apple, Google, Alexa and Home Assistant) — it is the most future-proof investment, as with the Matter-compatible smart home hubs we recommend.

Battery life and power

A battery-powered sensor (CR2032/CR2450) lasts 1.5–2 years and can be placed anywhere; a mains-powered sensor (FP2) offers advanced features but needs a nearby outlet. For hard-to-reach rooms, favour battery: changing one battery a year is less painful than recharging.

Settings: lux meter, delay, sensitivity

The three settings that make the daily difference: the lux meter (does not turn on in daylight), the off-delay (from 10 s to 30 min) and sensitivity (anti-false-alert). Check they are accessible in the app before buying: some cheap sensors only offer the delay.

Buying guide by scenario

🏠 Securing an entire home

Combine door/window sensors on doors and windows, a Bosch or Aqara motion sensor in the main hallway, and a subscription-free alarm for the siren: budget €150–250 for a complete perimeter with no monthly fees.

💡 Automating lighting on a budget

For the entrance, hallway and staircase: SwitchBot (€15) or Aqara P2 (€35) + a smart bulb. For full light scenes, the Philips Hue Motion Sensor remains the smoothest — see our smart light switch comparison to complete the setup.

🍎 Apple / HomeKit home

Eve Motion or Aqara P2 over Matter over Thread: no proprietary hub, a single Apple TV or HomePod border router is enough. For static presence in the office, the Aqara FP2 (Zigbee via Aqara hub) also works with HomeKit through a bridge.

🐕 Home with pets

Classic PIR sensors trigger on a passing cat. The Bosch (reliable pet mode), the Aqara FP2 (exclusion zones + pet mode) and sensors with adjustable sensitivity are the best choices. Avoid cheap PIRs without settings in rooms where pets roam at night.

Installation: our step-by-step tips

1. Pick the location: 2–2.5 m high, in a corner, with a clear field of view over the area to monitor. Avoid heat sources (radiator, direct sun), air vents and draughts.
2. Check the range: a PIR covers 5–9 m and 80–120°; for a long hallway, place the sensor at the end, not in the middle.
3. Mount it firmly: included adhesive on a clean surface, or screws/magnet if supplied. A sensor that moves = false alerts.
4. Pair it: scan the QR code in the app, add it to a room, test detection by walking through the zone.
5. Configure: sensitivity, off-delay, lux meter (day/night), time ranges (away mode at night for the alarm).
6. Test the automations: create a scene (light + notification) and check the real trigger before leaving on holiday.
