The Sonoff SenseGuard Motion Gen2 is a Zigbee PIR motion sensor designed to provide smarter and more energy-efficient home automation. It delivers instant motion detection in less than 3 seconds and features an adjustable detection duration from 5 to 60 seconds to reduce unnecessary triggers and optimize automations.
Equipped with an independent light sensor, it accurately measures ambient light levels, records up to 6 months of lighting history, and enables more precise lighting control based on environmental conditions.
With a 120° detection angle and a range of up to 6 meters, the sensor provides reliable indoor coverage. It can also be integrated into security scenarios to trigger alarms, send notifications, or start camera recordings when motion is detected.
