C4002 – BME280 – ENS160 Air Quality
Capable of detecting individuals who are sitting, sleeping, or standing completely still. Ideal for bedrooms, offices, and bathrooms.
Motion Detection: Up to 11m (Walking / Running).
Static Detection: Up to 10m (Reading / Typing / Sleeping).
Smart Lighting Automation: Maintains lighting based on true presence (breathing/micro-motion) rather than large movements, solving the problem of lights turning off while reading or working.
Privacy-Friendly Elderly Care: Detects presence or prolonged inactivity in bedrooms or bathrooms without the need for invasive cameras or wearable devices.
Plug-and-Play Smart Home Integration: BME280 Environmental Compensation. Integrated barometric sensor automatically corrects ENS160 readings for altitude and weather effects, improving accuracy by 30% versus standalone sensors.
To prevent false triggers common in radar technology (e.g., swaying plants, moving curtains), the C4002 incorporates adaptive background noise learning. The module automatically establishes a noise model of the environment, filtering out non-human interference to ensure triggers occur only upon actual human presence.
