Vandal-proof outdoor sensor (PIR/Ultrasonic/Sound). Dual relays for entrance control.

The Microwave & 3-PIR Wall Mount Active Occupancy Sensor is a high-precision, dual-technology presence detection device designed for smart buildings, commercial spaces, and industrial automation environments. By combining microwave Doppler detection with three independent PIR (Passive Infrared) sensing zones, this sensor delivers exceptional accuracy, extended coverage, and minimal false triggering.

The microwave sensor detects fine motion and presence through Doppler reflection, while the 3-PIR array ensures reliable human movement detection across multiple angles. This hybrid sensing approach makes the device ideal for corridors, offices, classrooms, warehouses, lobbies, washrooms, and parking areas.

Designed for wall-mount installation, the sensor supports active occupancy logic, ensuring lights or systems remain ON while occupants are present—even with minimal movement. It integrates seamlessly with lighting control systems, HVAC controllers, PLCs, and building management systems (BMS) via standard control interfaces.

With adjustable sensitivity, hold time, and lux threshold, the sensor enables optimized energy savings, automation accuracy, and occupant comfort. Industrial-grade electronics ensure stable performance in electrically noisy environments.
