Intelligent Infrared Body Sensor with ZigBee 3.0 Wireless Connection and 120° Detection Angle

This infrared detector (model Ih-K 0010) provides a wireless solution for monitoring movement within your smart home environment. It uses passive infrared technology to detect body heat and motion, making it suitable for security applications, lighting automation, or occupancy sensing. The sensor communicates via the ZigBee 3.0 protocol, a reliable low-power wireless standard compatible with many smart home ecosystems. This eliminates the need for running cables while maintaining a stable connection to your home automation hub. With its neutral white housing and compact dimensions, the sensor blends discreetly into various room settings, from hallways and living rooms to bedrooms and home offices.

Features and Construction

The sensor combines a practical detection specification with straightforward wireless connectivity. Its design prioritises reliable motion sensing within a defined area while maintaining a low-profile appearance. The construction balances technical functionality with installation simplicity, requiring only mounting and pairing rather than complex electrical work.

Material and Build

The sensor is housed in a white outer casing, which provides a neutral appearance suitable for most interior colour schemes. This finish helps the unit blend with walls or ceilings rather than standing out conspicuously. The housing protects the internal infrared detection components and supports the device's 28-gram weight, making it light enough for secure mounting with the included hardware. The build focuses on housing the necessary electronics for motion detection and wireless communication within a minimal footprint.

Size and Practical Fit

With dimensions of 33mm by 28mm, the sensor occupies minimal space on your wall or ceiling. This compact size allows for placement in discreet locations—above doorways, in room corners, or on ceiling surfaces—without becoming visually intrusive. The 28-gram weight ensures it stays securely mounted without requiring heavy-duty fixtures. The sensor's physical profile is designed to provide its technical functionality while respecting your interior space, making it suitable for both residential and light commercial environments where aesthetics matter alongside security.

Uses and Placement

The infrared sensor serves multiple roles in a connected home, from basic security to automated convenience. Its wireless nature and wide detection angle offer flexibility in how and where it's deployed. Understanding its capabilities helps determine optimal placement to achieve your specific monitoring or automation goals.

Event or Professional Use

In security-focused applications, the sensor can trigger alerts when unexpected motion is detected during certain hours, providing peace of mind whether you're away or asleep. Its 5-metre range and 120° angle allow it to monitor typical room dimensions effectively. For professional settings like small offices or retail spaces, multiple sensors can create a coordinated detection network without extensive wiring work. The -10°C to 45°C operating temperature ensures reliability in various indoor climates, including occasionally unheated spaces like garages or storage rooms that still require monitoring.

Everyday Home Use

For daily automation, the sensor can control lighting—turning lights on when someone enters a room and off after they leave—saving energy while adding convenience. It can also contribute to occupancy-aware heating or cooling systems, helping manage home efficiency. Placed in hallways, staircases, or children's rooms, it provides subtle monitoring without cameras. The ZigBee 3.0 connectivity allows integration with voice assistants and smart home routines, enabling scenarios like "goodnight" modes that arm sensors when you go to bed.

Benefits and Buying Value

Choosing this sensor involves considering its specific capabilities relative to your home automation needs. Its value comes from combining reliable detection with wireless convenience in a compact form factor. Unlike wired sensors, it offers installation flexibility without compromising on detection performance.

Reuse and Low Maintenance

The sensor is designed for long-term use once installed, with no consumables beyond occasional battery replacement via the included battery pin. Its solid-state construction with no moving parts minimises points of failure. The ZigBee protocol's mesh networking capability means the sensor can help extend the range of other ZigBee devices in your home, potentially improving your overall network reliability. The neutral white colour ensures it remains visually appropriate even if you redecorate, avoiding the need to replace sensors purely for aesthetic reasons.

Why Choose This Product

This infrared detector offers a balance of effective detection specifications and wireless convenience. The 120° angle and 5-metre range provide meaningful coverage for most residential rooms without requiring multiple sensors for basic areas. ZigBee 3.0 ensures compatibility with current and future smart home systems that support this widespread standard. The complete package includes all necessary components for installation—sensor, battery pin, and manual—so you can begin using it immediately. For those seeking to add reliable motion sensing to their smart home without complex wiring, this sensor presents a practical, specification-backed solution.
