Choose a sensor by what it detects

Motion, presence, opening, climate, leaks, smoke or gas?

A sensor is most useful when it answers a clear question and triggers a sensible next action. Start with the event—movement, presence, an opening, a leak or a change in the room—then choose the device.

Aqara Presence Sensor FP300

Is anyone here?

Use motion sensors for movement through a space, or presence sensors when the home must know that someone remains in the room.

Motion sensor or presence sensor?

Motion detects movement. Presence detects continued occupancy.

This is the most important choice in the range. A motion sensor is fast, small and battery-efficient. A presence sensor is designed to keep detecting a person after the obvious movement stops.

Aqara PIR motion sensor positioned in a HomeSmart project

Best for movement and passage

Choose a motion sensor

PIR motion sensors react when a person moves across their detection area. They are wire-free and well suited to places where people normally pass through rather than remain still.

  • Corridors, stairs, entrances, storerooms and wardrobes
  • Turning lights on quickly when movement begins
  • Battery-powered placement without a nearby outlet

Aqara presence sensor monitoring occupancy in a bedroom

Best for occupied rooms

Choose a presence sensor

mmWave presence sensing can recognise small movements from someone working, reading, watching television or resting. It helps prevent lights or air-conditioning from turning off while the room is still occupied.

  • Living rooms, bedrooms, studies and other longer-stay spaces
  • Reliable presence and absence automations
  • Zone-level control with FP2, or simple room occupancy with FP1E and FP300
FP1E — simple powered presenceFP2 — mapped zonesFP300 — battery multi-sensor

Presence is not automatically better everywhere. Use it where still occupancy matters. A compact motion sensor is often the cleaner, faster and more economical answer for passageways and short-use areas. Mixing both sensor types around one home is normal.

Compare Aqara sensor types

Choose the sensor for each room and automation.

The same household can use several kinds of sensors. These groups show what each current model contributes before you compare detailed specifications on its product page.

Presence and motion

Automate lighting, comfort and energy use from movement or continued occupancy.

Motion Sensor P1Zigbee · battery

Configurable PIR motion detection with adjustable timeout and sensitivity. A straightforward choice for fast passage and room-entry automations.

Motion and Light Sensor P2Thread · battery

Thread/Matter PIR motion and light sensing. Choose it when the intended ecosystem has a compatible Thread border router and Matter controller.

Presence Sensor FP1EZigbee · USB power

Simple room-level mmWave presence and absence sensing without zone mapping. Best when reliable still occupancy is the main requirement.

Presence Sensor FP2Wi-Fi · USB power

Maps up to 30 zones in a room and can detect multiple people. Choose it for location-based automations rather than a single occupied/unoccupied signal.

Presence Sensor FP300Zigbee or Thread · battery

Combines PIR and mmWave with light, temperature and humidity sensing. A wire-free presence option with protocol choice.

Doors, windows and objects

Know whether an opening or object changed state, then alert the household or run an automation.

Door and Window Sensor T1Zigbee · contact sensor

Compact two-part sensor for open and closed states on doors, windows, cupboards and other suitable openings.

Door and Window Sensor P2Thread · contact sensor

Matter-over-Thread alternative for openings. It needs a compatible Thread border router and Matter controller.

Vibration Sensor T1Zigbee · movement

Detects vibration, movement and drop events on a suitable object, drawer or window where a contact sensor is not the right signal.

Multi-State Sensor P100Zigbee or Thread · multi-state

Choose either open/close mode or object-monitoring mode. It can learn position and report selected orientation, movement, fall or vibration events.

Aqara climate sensor displaying room temperature and humidity

Climate and comfort

Use measured room conditions as context for air-conditioning, ventilation, alerts and everyday comfort.

Temperature and Humidity Sensor T1Zigbee · compact

Small battery sensor for temperature, humidity and air-pressure readings without a display.

Climate Sensor W100Zigbee or Thread · display

Adds a large temperature and humidity display and three control buttons. Zigbee mode unlocks its fuller Aqara Home functions.

Aqara water leak sensor positioned near a potential leak point

Leaks, smoke and gas

Place detectors near the hazard they are intended to recognise, not merely where they are easy to see.

Water Leak Sensor T1Zigbee · battery

Detects water across its underside contacts. Place near washing machines, sinks, water heaters or other credible leak points.

Smart Smoke DetectorZigbee · local siren

Detects smoke, sounds a local warning and can send remote notifications through the connected Aqara system.

Smart Gas DetectorZigbee · local siren

Designed for combustible-gas detection with a local alarm and connected notifications. Suitability depends on gas type and installation conditions.

Zigbee, Thread or Wi-Fi

Choose the right sensor protocol for your hub and platform.

Protocol affects the hub or controller required and which advanced settings remain available. Choose the ecosystem first; do not buy a Thread model simply because it is newer.

Aqara Zigbee sensors

Use a compatible Aqara Zigbee hub. This is usually the most direct route to full Aqara Home settings, local automations and a broad range of Aqara devices. Selected hubs can bridge supported devices into Apple Home and other Matter ecosystems.

Thread and Matter sensors

Need a compatible Thread border router and Matter controller. Dual-protocol models such as FP300, W100 and P100 can instead be added in Zigbee mode; features may differ between modes and a device cannot use both modes at the same time.

FP2 is the exception in this range: it connects directly by Wi-Fi and does not need an Aqara hub for its core zone-presence functions. Its USB power and placement still need planning.

Sensor placement and automation planning

Place the sensor where it can detect the right event.

A good sensor plan is not “one in every room”. Each device should have a defined detection area, a compatible connection and a response that still makes sense during normal life.

1
Name the eventMovement, continued presence, opening, water, smoke, gas, temperature or a change in an object's state.
2
Test the physical positionCheck detection angle, range, reflective surfaces, moving curtains, pets, likely water path and the gap between contact-sensor parts.
3
Confirm power and connectionBattery, USB power, Zigbee hub, Wi-Fi or Thread/Matter infrastructure must all work at the actual installation point.
4
Define a useful responseTurn on a light, adjust cooling, send a meaningful alert, sound a siren or wait for a second condition before acting.

Smart sensor automation examples

Use sensor readings to control lights, comfort and alerts.

The most useful automations combine the right sensor with time, light level, home mode or another condition, so the response fits what is really happening.

Lighting that follows use

Turn on corridor lights when motion begins, keep a study lit while presence remains, or use measured light level so daytime movement does not trigger unnecessary lighting.

Comfort without guesswork

Use occupancy, temperature and humidity as conditions for air-conditioning or ventilation, then stop or adjust them when the room is genuinely empty.

Alerts that deserve attention

Notify on a door opening while away, water where it should not be, or a local smoke or gas alarm. Schedules and modes keep routine activity from becoming noise.

Frequently asked questions

Smart sensor questions.

What is the difference between a motion sensor and a presence sensor?

A PIR motion sensor reacts to movement and is ideal for corridors, entrances and short-use spaces. A presence sensor uses mmWave, or combines mmWave and PIR, to detect smaller movements from someone who remains seated or still. Use presence sensing where lights or air-conditioning must stay on while a room remains occupied.

Do Aqara sensors need a hub?

Most do, but the required infrastructure differs. Zigbee sensors need a compatible Aqara Zigbee hub. Thread sensors need a compatible Thread border router and Matter controller. Dual-protocol models can be commissioned in either Zigbee or Thread mode. FP2 connects directly by Wi-Fi for its core functions.

Should I choose Zigbee or Thread sensors?

Choose for the ecosystem and features you plan to use. Zigbee is the established route to Aqara Home features and local Aqara automations through an Aqara hub. Thread/Matter can connect through compatible third-party ecosystems, but controller requirements and available settings differ. A newer protocol is not automatically a better fit.

Which presence sensor should I choose: FP1E, FP2 or FP300?

Choose FP1E for simple powered room-level presence through Aqara Zigbee. Choose FP2 when you need mapped zones, multi-person positioning or a direct Wi-Fi connection. Choose FP300 for wire-free installation with combined PIR/mmWave presence plus light, temperature and humidity sensing, using either Zigbee or Thread.

Can smart sensors work without internet?

Many Aqara Zigbee automations can run locally through a compatible hub after setup, but exact behaviour depends on the devices, hub and chosen ecosystem. Remote notifications and app access from outside the home generally require internet access.

Where should I place a water leak sensor?

Place it on a level surface where water is likely to collect early: near a washing machine, under a sink, beside a water heater or close to another credible leak point. Its contacts must be able to reach the water; placing it somewhere merely visible may not provide early detection.

Can I mix different sensor types in one home?

Yes. Motion sensors suit passageways, presence sensors suit occupied rooms, contact sensors monitor openings, and climate or safety sensors answer different questions. A well-planned home normally combines them rather than forcing one sensor type everywhere.

Can HomeSmart help install and configure smart sensors?

Yes. HomeSmart can help select compatible sensors, plan locations, install suitable devices, connect them to the intended hub or platform and configure agreed alerts, scenes and automations. Site conditions and any additional electrical work are quoted separately.
