This Wi-Fi motion sensor employs a passive infrared detection principle, utilizing a high-sensitivity PIR element paired with a 128-degree wide-angle lens and an 8-meter detection range. The sensor’s housing is constructed from durable ABS plastic with a matte finish, offering resistance to minor impacts and everyday wear. The internal circuitry is designed for stable operation, with low-power consumption that supports either battery or USB power inputs. The unit’s compact form factor allows for flexible placement on walls, corners, or shelves without obstructing interior aesthetics. The detection algorithm is calibrated to reduce false triggers from small pets or environmental changes, providing reliable real-time alerts directly through the Smart Life or Tuya app. No additional hub or bridge is required; the device connects directly to a 2.4GHz Wi-Fi network, making setup straightforward for most home networks. The sensor’s response time is consistent, with notifications arriving within seconds of detected movement. The build quality emphasizes longevity, with reinforced mounting brackets and a securely sealed battery compartment. For users seeking a cost-effective entry into home security automation, this motion detector offers core functionality without compromising on hardware reliability. The lens design provides even coverage across the wide field, minimizing blind spots in corners. Power flexibility is a key attribute: the device can be powered by two standard AA batteries for cordless placement or via a micro USB cable for continuous operation. The absence of a hub reduces overall system complexity and upfront costs. The sensor integrates seamlessly with existing Smart Life/Tuya ecosystems, enabling conditional automation such as triggering lights or alarms. The app interface displays battery status, signal strength, and event logs. The firmware supports over-the-air updates for continued performance improvements. While the detection range is adequate for most indoor rooms—such as living areas, hallways, or garages—the 8-meter maximum works best in spaces without heavy obstacles. The 128-degree angle covers a broad arc, suitable for monitoring entry points or open-plan zones. The device’s affordability, at a very low price point, makes it accessible for multi-unit deployments. The materials and assembly are consistent with mass-market smart home devices, offering a balance between cost and durability. The sensor operates effectively in typical household temperatures and lighting conditions, with no performance degradation reported under normal use. The product is compatible with Amazon Alexa and Google Assistant through the Tuya platform, allowing voice control integration. The wireless transmission range depends on the router environment, but the device supports standard Wi-Fi protocols for stable connectivity.

This sensor delivers essential motion detection features in a straightforward, hub-free package suitable for budget-conscious home automation projects.
