Intelligent Infrared Body Sensor with 120-Degree Detection and 5-Metre Range for Home Security

This intelligent infrared body sensor provides practical motion detection for home security and automation applications. Using infrared technology, it detects movement within a wide 120-degree field of view across distances up to 5 metres. The sensor connects wirelessly via ZigBee 3.0 protocol, making it compatible with modern smart home ecosystems. Its compact dimensions of 33mm by 28mm allow for discreet installation while the neutral white housing blends with various interiors. Operating within a temperature range of -10°C to 45°C ensures reliable performance in different room environments without specialist climate control requirements.

Features and Construction

The infrared body sensor combines practical detection capabilities with straightforward installation. Its construction prioritises reliable motion sensing while maintaining a minimal visual presence in living spaces.

Material and Build

The sensor features a white plastic housing that provides protection for the internal components while maintaining a neutral appearance suitable for most interior décors. Inside, infrared detection elements work alongside a ZigBee 3.0 wireless module that handles communication with compatible hubs and controllers. The 28g weight makes it lightweight enough for various mounting options without requiring heavy-duty fixtures.

Size and Practical Fit

Measuring just 33mm by 28mm, the sensor's compact dimensions enable installation in spaces where larger detectors might be visually intrusive. This size allows placement above doorways, in corners, or alongside existing fittings without dominating the area. The detection range of up to 5 metres provides coverage for medium-sized rooms, while the 120-degree angle ensures broad coverage from a single mounting point.

Uses and Placement

The infrared sensor serves both security and automation functions in residential settings. Its detection capabilities can trigger various responses depending on system configuration and user preferences.

Event or Professional Use

For security applications, the sensor can trigger alerts when unexpected motion is detected during specific time periods. The ZigBee 3.0 connectivity allows integration with professional monitoring systems or comprehensive home security setups. The temperature tolerance from -10°C to 45°C ensures operation in different climate zones within a building, from cooler basements to warmer upper floors.

Everyday Home Use

In everyday smart home scenarios, the sensor can automate lighting, climate control, or entertainment systems based on room occupancy. The wireless connectivity eliminates the need for running cables during installation. Placement considerations include ensuring the 120-degree detection angle covers the desired area without obstructions and positioning within the 5-metre range of the target zone.

Benefits and Buying Value

This infrared body sensor offers practical motion detection with straightforward integration into existing or new smart home setups. Its specifications provide measurable performance parameters for informed placement decisions.

Reuse and Low Maintenance

The sensor's wireless design allows for repositioning as needs change without rewiring. The specified temperature range supports use in various rooms throughout the year. The included battery pin suggests user-replaceable power components, though specific battery life details would depend on usage patterns and environmental factors.

Why Choose This Product

The combination of 120-degree detection angle and 5-metre range provides measurable coverage parameters for planning sensor placement. ZigBee 3.0 connectivity offers compatibility with modern smart home ecosystems without proprietary limitations. The compact 33mm by 28mm size enables discreet installation where larger detectors might be visually prominent, while the neutral white housing suits most interior colour schemes.
