Overview
24GHz mmWave Radar
Product Characteristics
Human Presence Detection
Operating at 24GHz with a wavelength of just 12.5mm, the sensor captures micro-displacements as subtle as breathing and heartbeat. It reliably detects human presence even when the body is still. Millimeter waves penetrate common materials such as drywall, wood panels, and plastic housings, enabling concealed installation. Unaffected by light, temperature, or dust, it delivers truly 24/7 presence detection.
Precise Ranging
Using FMCW technology, the sensor achieves centimeter-level ranging accuracy, precisely locking target position. It supports zone-based triggering of different device responses by distance, enabling refined spatial coordination.
Trajectory Tracking
Based on multiple trajectory correlation algorithms, the sensor fits and predicts target motion paths in real time, outputting continuous and smooth position data. Multiple angular zones are defined within the horizontal field of view to precisely identify target orientation. Movement direction is also detected: approaching triggers wake-up, departing triggers shut-off, enabling refined spatial coordination based on both angle and direction.
Smart Bathroom
24G millimeter-wave radar enables seamless automation for whole-house lighting, fans, curtains and more. Lights turn on upon human entry and off when people leave, requiring no voice or mobile control. The sensor can be discreetly embedded inside appliance housings to equip devices with spatial awareness: home appliances wake automatically on human approach and switch to energy-saving standby after departure; fans adjust airflow direction based on human positions.
Smart Bathroom
Millimeter-wave radar penetrates toilet lids and plastic housings to deliver a fully contactless user experience. It automatically lifts the lid on approach, activates seat heating upon seating, and maintains reliable continuous human presence detection. The toilet performs auto flushing and deodorization after users leave; additionally, it identifies male urination movements to trigger dedicated small-volume flushing.
