Detects human presence via obstacle distance (no movement needed). Ideal for bathrooms.

The Ultrasonic Presence Detector with Sound Sensor (G4) is an advanced occupancy and motion detection module engineered for high-accuracy indoor automation applications. By combining ultrasonic wave detection with a sound-based sensing mechanism, this device detects human presence even when there is little or no visible movement, outperforming traditional PIR sensors.

The ultrasonic sensor emits high-frequency sound waves and analyzes reflected signals to identify micro-movements, while the integrated sound sensor adds an extra layer of detection for enhanced reliability. This dual-sensor approach ensures accurate occupancy detection, reduced false triggers, and consistent performance in offices, conference rooms, corridors, washrooms, and commercial buildings.

Built on G4 (Generation 4) hardware, the module offers stable operation, excellent noise resistance, and seamless integration with S-BUS-based automation systems. Its compact, industrial-grade design makes it ideal for smart lighting control, HVAC optimization, security systems, and energy-efficient building management solutions.
