The Sonoff SNZB-03PR2 is a second-generation SenseGuard motion sensor designed to automate your home using Zigbee 3.0 technology. It utilizes a passive infrared sensor to detect movement within a 120-degree angle and a range of up to 6 meters, making it useful for triggering lights or security alerts when someone enters a room. To prevent constant triggering, you can adjust the cooldown time between 5 and 60 seconds. Beyond motion detection, this device features an integrated lux sensor that measures ambient light levels and maintains an illumination history for up to six months. The compact polycarbonate housing measures 44 x 44 x 65 mm and weighs 42.7 g, powered by a CR2477 3V battery that lasts approximately three years. You can install it at a height of up to 2 meters using the included magnetic base, 3M adhesive, or screws. This sensor works with various hubs, including eWeLink, Home Assistant, Amazon Alexa, and SmartThings, providing a communication range of 100 meters in open areas. It is built to operate in temperatures from -10°C to 60°C, ensuring reliability in different indoor environments.
