SEN0691

SEN0691 is a 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 10×10meter range, this module serves as a reliable core component for smart lighting, HVAC control, and security monitoring in Home Assistant and IoT systems.

• Streamlined home assistant integration, true static presence detection (10x10m range)
• Precision control for complex environments, intelligent environmental filtering
• Operating voltage range from 3.6 to 5.5V and detection angle: 120° x 120°
• Detection capability: motion, micro-motion /stationary human body
• Max detection distance: motion 11m, micro-motion/stationary 10m
• Output interface: OUT (configurable IO), UART
• Operating frequency range from 24GHz to 24.25GHz
• Light detection: 0 to 50lux
• Operating temperature range from -20 to 85°C
• Product dimension is 22mm x 26mm
