Intelligent wireless infrared body sensor with ZigBee 3.0 connectivity and 120-degree detection angle

This compact infrared body sensor provides wireless home security monitoring through ZigBee 3.0 technology, eliminating the need for complex wiring installations. Measuring just 33mm x 28mm and weighing 28g, the white-cased device offers discreet placement options throughout the home while maintaining reliable movement detection capabilities. With a 120-degree detection angle and range extending up to 5 metres, it covers significant areas for security purposes or home automation triggers. The sensor operates effectively across a temperature range from -10°C to 45°C, ensuring consistent performance in various indoor environments where monitoring human presence is required.

Features and Construction

The sensor combines wireless connectivity with precise infrared detection technology in a minimal footprint design suitable for modern smart homes.

Material and Build

Constructed with a neutral white outer casing that measures 33mm by 28mm, the sensor maintains a low-profile appearance that blends with most interior décors. The compact design weighs just 28g, allowing for placement on various surfaces without requiring substantial support. Internal components include infrared detection technology paired with ZigBee 3.0 wireless communication modules, all powered by battery rather than mains electricity. This construction approach enables flexible installation locations without proximity to power outlets being a limiting factor.

Size and Practical Fit

With dimensions of 33mm x 28mm, the sensor occupies minimal space while providing substantial detection capabilities through its 120-degree angle coverage. The 28g weight ensures it can be mounted securely using appropriate adhesives or fixtures without straining surfaces. The 5-metre detection range allows coverage of medium-sized rooms or corridors from strategic placement points. This combination of compact physical size with effective detection parameters makes the sensor suitable for monitoring entryways, hallways, or specific zones within living spaces where wireless, discreet monitoring is preferred.

Uses and Placement

The sensor's wireless nature and detection specifications support various home monitoring applications from security to automation.

Event or Professional Use

For security-focused applications, the sensor can monitor movement in areas during specific time periods, potentially triggering alerts or recordings through connected smart home systems. The ZigBee 3.0 connectivity allows integration with compatible security hubs or automation controllers for professional monitoring setups. The 120-degree detection angle provides sufficient coverage across doorways or room entrances when positioned at appropriate heights and angles. Operating between -10°C and 45°C ensures reliable performance in various indoor climates, including occasionally unheated spaces like garages or storage areas that might require monitoring.

Everyday Home Use

In residential settings, the sensor enables automation scenarios like lighting control upon detecting movement in frequently used areas during evening hours. Its wireless design simplifies installation compared to wired alternatives, particularly in rented properties or where drilling is not preferred. The neutral white colouring helps the device blend with most wall colours and interior styles when placed in living areas. For multi-sensor setups, the compact size allows placement of several units throughout a home without creating visual clutter, supporting comprehensive coverage of movement patterns for energy efficiency or convenience applications.

Benefits and Buying Value

The sensor offers practical advantages through its specifications and connectivity approach rather than requiring complex installation procedures.

Reuse and Low Maintenance

As a wireless device, the sensor can be repositioned as home layouts change or monitoring needs evolve, without leaving wiring痕迹. Battery-powered operation reduces ongoing electricity costs compared to constantly powered alternatives, though batteries require periodic replacement as indicated by the included battery pin for checking connection status. The ZigBee 3.0 standard supports communication with various compatible devices, potentially extending the sensor's usefulness as smart home ecosystems expand. The temperature operating range from -10°C to 45°C ensures the device functions in most indoor environments without requiring climate-controlled conditions.
