The LD2450 Human Body Perception Module uses 24 GHz millimeter-wave radar to detect human presence and micro-movements that traditional sensing methods may miss. It provides stable performance across different environments and can be concealed inside a housing without surface openings, enhancing product aesthetics. Key benefits - Detects human presence and subtle movements that other sensors may overlook - Excellent environmental adaptability: performance is not affected by temperature, glare, moisture, or lighting fluctuations - Concealed installation: high shell penetration allows the module to operate inside a housing without visible holes - Reliable target localization and monitoring for sensor-based applications - Widely applicable across a range of scenarios and use cases Core capabilities - 24 GHz millimeter-wave radar sensor - Sensitive to human bodies and micro-movements - Robust environmental performance across varying conditions - Concealed operation with no surface openings required - Accurate target locating and monitoring for sensor-based systems Application scenarios - Smart Home - Smart Trade (Smart Commerce) - Bathroom - Smart Lighting - Other general sensing and monitoring applications Practical use cases - Occupancy-based lighting and energy management in residential and commercial spaces - Non-contact presence monitoring to support smart home automation without visible sensors - Presence detection in bathrooms for safe, automated control and usage analytics - Retail presence sensing to optimize signage, displays, and environmental settings
