The HDL M/WS05.1 KNX Wall Mount Outdoor Microwave Sensor is a rugged multi-function sensor for exterior and harsh-environment applications. It combines microwave motion detection with integrated brightness, temperature, and humidity measurement, plus two dry-contact inputs — all on the KNX bus with built-in logic for lighting, curtain, and threshold automation.

The sensor provides four independent logic blocks and one combined block, each with up to 10 target outputs. Logic inputs include microwave status, lux value, temperature, dry contacts, and external telegrams, with AND/OR relations. It supports single mode and master/slave mode for scalable coverage of large outdoor areas, with a microwave detection range of Φ28 m at 3 m installation height.

Key Features — Outdoor Multi-Sensor with Logic

Integrated Sensors

• Microwave motion: Φ28 m detection diameter at 3 m height.
• Brightness (lux): 0–35,000 lux measurement range.
• Temperature: −30 °C to +70 °C.
• Humidity: 20–95 % RH.
• Dry contacts: 2 inputs — configurable as contacts or LED status indicators.
• External telegrams: Logic validity and lock/unlock via KNX telegrams.

Control and Logic

• 5 logic blocks: 4 independent + 1 combined; 10 object outputs each.
• 2CH constant-light control: 4 preset constant values with forced-operation dimming.
• Automatic / semi-automatic mode: Configurable operating behaviour.
• Master / slave mode: Extend detection coverage across multiple sensors.
• Control types: Switch, absolute dimming, curtain, alarm, percentage, sequence, scene, string (14 byte), logic combination.
• Dry-contact outputs: Target control as switch, dimming, or scene.

Applications and KNX Integration

• Building perimeters and car parks: Microwave detection with lux-linked lighting control for energy saving.
• Warehouses and industrial facades: IP54 housing for dust and splash-water resistance.
• Facade and landscape lighting: Constant-light control from integrated lux sensor.
• Indoor alternative: For compact ceiling PIR in offices and corridors, use the HDL M/IS05.1 Mini PIR Lux Sensor.
• Load control: Pair with HDL MOSFET dimming actuators or M/R16.10.1 switch actuators for automated lighting and curtain response.
• EAE comparison: For KNX presence detection with built-in lux, see the EAE PD100 Presence Detector.

Choosing HDL Sensors

The M/WS05.1 is HDL's outdoor wall-mount microwave sensor — IP54, wide Φ28 m range, humidity measurement, and dry contacts. HDL also offers the same model family in ceiling-mount indoor form for IP20 interior applications. For discreet flush ceiling PIR in rooms, choose the M/IS05.1.
