The Sonoff SNZB-03P is a Zigbee 3.0 motion sensor designed to automate your home by detecting movement using passive infrared technology. It can sense activity within a range of 6 meters and a wide 110-degree angle, reacting quickly with a detection speed of 5 seconds to trigger smart scenes or send instant notifications to your phone via the eWeLink app. This compact device is housed in a white PC shell measuring 44 x 44 x 65 mm and weighing just 54 g, making it discreet enough to place in any room. It operates reliably in temperatures ranging from -10°C to +60°C and is powered by a CR2477 battery that lasts for over 3 years, reducing the need for frequent maintenance. To function, the sensor requires a compatible Zigbee hub, such as the Sonoff Zigbee Bridge or iHost, and integrates easily with Amazon Alexa, Google Assistant, and SmartThings. Because it supports local smart scenes, your automated routines will continue to work even if your WiFi connection is interrupted, provided the hub remains powered.
