The Microwave & 3PIR Wall Mount Active Occupancy Sensor (G4s) by Rob Gold is an advanced dual-technology motion and presence detection sensor designed for precise and reliable space occupancy monitoring. Combining Microwave radar sensing with triple PIR (Passive Infrared) technology, it ensures ultra-accurate detection of motion and human presence — even in complex environments.

This 2-in-1 intelligent occupancy sensor uses active microwave signals to detect movement through obstacles, while 3 PIR elements capture subtle body heat variations for complete area coverage. The G4s control platform provides high-speed data communication, stable performance, and easy integration with smart automation systems, BMS, lighting controls, and HVAC systems.

Perfect for offices, conference rooms, hotels, schools, and commercial buildings, this sensor optimizes energy efficiency, enhances comfort, and ensures accurate occupancy control.
