Fermion: C4002 mmWave Human Presence Sensor - Static & Motion Detection for Home Assistant (10m)
Beyond Traditional PIR Limits, delivers "True Presence" Automation with Micro-Motion Detection. Traditional PIR sensors often fail to detect stationary occupants, leading to inconvenient lighting deactivation. The Fermion: C4002 mmWave radar module resolves this by utilizing 24GHz FMCW technology to detect micro-motions (such as breathing and chest expansion). Capable of distinguishing between moving, stationary, and micro-moving targets within a 10×10 meter range, this module serves as a reliable core component for smart lighting, HVAC control, and security monitoring in Home Assistant and IoT systems.
User Manual / Datasheet / Example Codes Etc.
Applications
- 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.
- HVAC Energy Management: Automatically activates air conditioning or heating only when the room is actually occupied, optimizing energy efficiency in homes or offices.
- Privacy-Friendly Elderly Care: Detects presence or prolonged inactivity in bedrooms or bathrooms without the need for invasive cameras or wearable devices.
- Concealed Security: Capable of detecting intrusion through thin non-metal obstacles (like decorations or thin walls), allowing for a completely hidden security setup.
