ZigBee wireless infrared body sensor with 120-degree detection angle and 5-metre range for smart home security

This compact infrared body sensor utilises ZigBee 3.0 wireless technology to connect with compatible smart home systems, providing reliable movement detection for home automation and security applications. With a detection angle of 120 degrees and a range extending up to 5 metres, the sensor monitors substantial areas while maintaining discreet placement due to its small 33mm by 28mm dimensions. Operating effectively in temperatures from -10°C to 45°C, this sensor adapts to various indoor environments where temperature may fluctuate throughout seasons or between different rooms in a property.

Features and Construction

The infrared body sensor combines practical detection capabilities with straightforward wireless connectivity, creating a versatile component for smart home ecosystems. Its construction focuses on reliable performance within the specified operational parameters, ensuring consistent detection functionality across its temperature range.

Material and Build

Housed in a neutral white casing measuring 33mm by 28mm, the sensor presents a discreet appearance suitable for various interior settings. The casing contains infrared detection components that identify movement within the specified 120-degree angle, paired with ZigBee 3.0 wireless communication modules that transmit detection signals to connected systems. The complete unit weighs just 28 grams, contributing to minimal visual presence while maintaining functional reliability.

Size and Practical Fit

With dimensions of 33mm by 28mm, the sensor occupies minimal space, allowing placement in discreet locations such as corners, shelves, or near entry points without dominating the visual environment. This compact size facilitates installation in spaces where larger detection units might be impractical or visually intrusive. The 120-degree detection angle provides broad coverage from a single point, reducing the number of sensors required to monitor typical room areas effectively.

Uses and Placement

The sensor's combination of wireless connectivity and motion detection capabilities supports both security-focused applications and convenience automation within smart home environments. Its operational temperature range makes it suitable for installation in various indoor locations throughout a property.

Event or Professional Use

For event spaces or professional environments, the sensor can trigger lighting adjustments, climate control responses, or occupancy monitoring when integrated with appropriate automation systems. The 5-metre detection range allows coverage of larger areas like conference rooms, reception spaces, or commercial premises where movement detection informs energy management or security protocols. ZigBee 3.0 connectivity ensures reliable communication with professional-grade automation controllers.

Everyday Home Use

In residential settings, the sensor enables common smart home functions such as automatic lighting when entering rooms, security alerts for unauthorised movement, or presence-based heating adjustments. Homeowners can position sensors near entryways, in hallways, or in frequently used rooms to create responsive environments that adapt to household patterns. The temperature tolerance from -10°C to 45°C accommodates installation in potentially cooler spaces like garages or sunrooms as well as warmer areas like kitchens or conservatories.

Benefits and Buying Value

This infrared body sensor offers practical automation capabilities through its combination of wireless technology and reliable detection parameters. The product addresses specific needs within smart home ecosystems while maintaining straightforward installation and operation.

Reuse and Low Maintenance

The sensor's wireless design facilitates repositioning as needs change within a property, allowing homeowners to adapt their automation setup without extensive rewiring or structural modifications. With no moving mechanical parts and solid-state electronic construction, the unit requires minimal maintenance beyond occasional cleaning of the sensor surface. ZigBee 3.0's mesh networking capability means the sensor can form part of an expandable system where additional devices strengthen overall network reliability.

Why Choose This Product

This infrared sensor provides a balance between detection performance and integration ease, with its 120-degree angle and 5-metre range offering substantial coverage from a compact unit. The specified temperature operational range from -10°C to 45°C ensures reliable performance across most indoor environments without requiring climate-controlled spaces. For those building or expanding a ZigBee-based smart home system, this sensor delivers the core functionality needed for presence detection while maintaining compatibility with the ZigBee 3.0 standard for seamless integration.
