Measurement and detection9

Motion detection range — what it means The longest distance at which the sensor notices a walking person, as stated by the manufacturer. Real range depends on mounting height and direction: someone crossing the zone is noticed further away than someone walking straight at the sensor.	6 mAbout 6 m. With a large difference between ambient and body temperature (about 20 °C or more) the range may increase [1]
Horizontal detection angle — what it means How wide the zone covered by the sensor is, in degrees. In a room corner about 90° covers the full width; on a flat wall the same needs an angle closer to 180°.	110°About 110° per the specification table in manual V1.0 and the SONOFF Help Center [1]
Light sensing — what it means Lets motion turn the lights on only when it is dark. “In lux” means the sensor reports the light level as a number, so the threshold can be set precisely; “bright/dark” means only two states with a threshold set by the manufacturer.	Measures in luxA separate light sensor reports lux values, with calibration (±1000 lx offset) and up to 6 months of history. With some gateways (e.g. Amazon Echo) illuminance is not available [2]
Cooldown between detections — what it means How many seconds the sensor waits after a detection before reporting “no motion” and being able to trigger again. The adjustable range is shown (if it is fixed, minimum and maximum are equal): a short cooldown turns lights off sooner, a long one means fewer messages and less battery drain.	5–60 sAdjustable in eWeLink with a SONOFF gateway, in Home Assistant, and with Amazon Echo via the sensor button [2]
Detection technology — what it means PIR reacts to warm bodies moving and does not notice a person sitting still. In combined sensors a second sensor confirms or complements the PIR; how exactly is stated in the model description.	Passive infrared (PIR) [1]
Motion response time — what it means How many seconds after movement starts the sensor sends the event, as stated by the manufacturer. It decides whether the light comes on before a person has walked into the room.	3 sManufacturer: motion is detected within 3 s; the FAQ says linked actions trigger in as fast as 5 s [3]
Pet immunity, up to — what it means The heaviest pet the sensor should ignore when installed as instructed (mounting height and tilt are set by the manufacturer). If no value is published, the manufacturer does not claim this feature.	Not stated by the manufacturer
Sensitivity levels — what it means How many sensitivity settings can be chosen in the app or on the sensor. Lower sensitivity cuts false triggers, higher helps in large rooms; 1 means sensitivity cannot be adjusted.	Not stated by the manufacturer
Illuminance history	6 monthsWith data export in eWeLink [2]

Connectivity and compatibility11

Connectivity — what it means The wireless link or network the device uses. Wi-Fi connects straight to the router; Zigbee, Thread and Bluetooth Mesh work through a hub or gateway.	ZigbeeZigbee 3.0 [1]
Hub required — what it means Whether the device needs a separate hub, gateway or coordinator to work in a smart home. If so, it is sold separately unless stated otherwise.	RequiredNeeds a Zigbee 3.0 gateway. Recommended: SONOFF ZBBridge-P, ZBBridge-U, NSPanel Pro, iHost; also Amazon Echo Plus 2nd gen, Echo 4th gen, Echo Show 2nd gen and Aeotec Smart Home Hub V3 (with fewer functions) [2]
Matter support — what it means Whether the device supports the Matter standard, directly or through a bridge. Matter lets you add it to Apple Home, Google Home, Alexa and Home Assistant.	Via a Matter bridgeInto Apple Home via a Matter bridge: ZBBridge-U, iHost, NSPanel Pro or eWeLink CUBE [3]
Home Assistant — what it means How the device connects to Home Assistant: a built-in integration, a Zigbee coordinator, Matter or the maker’s cloud integration.	Via a hub or coordinatorVia a Zigbee coordinator: Zigbee2MQTT or ZHA (for ZHA the manufacturer provides a script to download); SONOFF ZBDongle-P/-E coordinators etc [2]
Wireless range — what it means The stated radio range, usually in open space. Walls and floors cut it noticeably.	100 mOpen area [1]
Processor / radio chip — what it means The microcontroller or radio module inside, per the maker (for example ESP32). For firmware such as WLED and ESPHome it determines available features and whether the device can be re-flashed.	TLSR8656 [1]
Radio frequencies and transmit power	2405–2480 MHz (Zigbee, IEEE 802.15.4)Band and power from the EU declaration in the manual [1]
Transmit power — what it means The coordinator's maximum radio output. Higher power gives a steadier link to distant devices, but range in a home depends more on walls and the number of routers in the network.	Zigbee ≤ 10 dBm [1]
Zigbee version	Zigbee 3.0 [1]
App — what it means The maker’s app used to set up and control the device.	eWeLink [1]
Third-party platforms (via eWeLink)	Alexa, Google Home, SmartThings, Sber, Alice, IFTTTAlexa, Google Home, SmartThings, Sber, Alice — motion status query; IFTTT (membership) — motion / no motion. Via eWeLink cloud integration with a SONOFF gateway [2]

Power3

Power source — what it means Where the device gets its power: 230 V mains, an adapter, USB, batteries or a built-in battery.	Battery [1]
Batteries or battery — what it means Which cells it takes and how many. A built-in rechargeable battery is stated in the value.	1 × CR2477 (3 V) [1]
Battery life — what it means Typical life on one set of batteries or one charge, per the maker. Frequent triggers, cold and a weak signal shorten it.	36 monthsUp to 3 years per the product page and Help Center; the first page of manual V1.0 says “2-year” [2]

Housing and installation8

Installation environment — what it means Where the manufacturer allows the sensor to be used. Indoor models are not built for rain, frost or direct sun.	Indoor [1]
Mounting — what it means How and where it is installed: in a wall box, on a wall or ceiling, on a DIN rail, on a table or in a socket.	Table or shelf, Magnetic, adhesive tape, Wall, CeilingMagnetic base included: desktop, on metal, 3M adhesive or screws to the wall. Flush ceiling mounting needs a housing sold separately. The manual limits mounting height to 2 m [1]
Adjustable head or bracket — what it means Whether the sensor can be turned after mounting to aim its detection zone, for example away from a pet bed or a window.	YesThe sensor head can be turned freely [3]
Housing dimensions — what it means The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.	44 × 44 × 65 mm [1]
Weight — what it means The device’s weight without packaging, per the maker.	42.7 gWith battery [1]
Housing material	PC (polycarbonate) [1]

In your home

First detect it. Then trigger the right routine.

A sensor reports measurements or events. What happens next depends on configuration and separate control devices.

What to check before buying

A seated person and a hallway need different detection settings. We tune detection zones, switch-off delays and familiar switches.
Power — Battery: plan it for the mounting spot.
