The HDL M/IS05.1 KNX Mini PIR Lux Sensor is a compact ceiling-mount multi-function sensor combining PIR motion detection, brightness (lux) measurement, and temperature sensing on a single KNX device. Its small form factor (Φ63 mm) suits flush or surface ceiling installation in offices, corridors, meeting rooms, and residential spaces.

The sensor includes five logic blocks with up to 10 object outputs each, supporting AND/OR relations and inputs from PIR status, lux value, temperature, and external telegrams. It provides 2-channel lighting control with gradual dimming, delay settings, and 2-channel constant-light control, operating in automatic, semi-automatic, single, or master/slave modes.

Key Features — Compact PIR, Lux, and Temperature

Integrated Sensors

• PIR motion: Φ8 m detection diameter at 3 m installation height.
• Lux sensor: Brightness measurement for daylight-linked control.
• Temperature sensor: Room temperature value on the KNX bus.
• External telegrams: Logic validity and lock/unlock via KNX telegrams.

Control and Logic

• 5 logic blocks: 10 object outputs each; AND/OR relations.
• 2CH lighting control: 4 brightness/delay sections, gradual dimming, auto/semi-auto mode.
• 2CH constant-light control: Preset dimming values and forced operation.
• Master / slave mode: Scalable detection for larger rooms.
• Control types: Switch, absolute dimming, shutter, alarm, percentage, sequence, scene, string (14 byte), threshold, logic combination.
• Telegram lock/unlock: Configurable on/off telegram on lock/unlock events.

Applications and KNX Integration

• Office and corridor lighting: PIR-triggered switching with lux-based constant-light dimming.
• Meeting rooms: Master/slave mode for consistent coverage in larger spaces.
• HVAC input: Temperature value available for room climate logic.
• Outdoor alternative: For exterior microwave detection with humidity and dry contacts, use the HDL M/WS05.1 Outdoor Microwave Sensor.
• Load control: Drive HDL MOSFET dimming actuators, M/DALI.1 gateway, or M/R16.10.1 switch actuators from sensor logic outputs.
• EAE comparison: For a dedicated KNX presence detector with PIR+F+S, see the EAE PD100.

Choosing HDL Sensors

The M/IS05.1 is the compact ceiling PIR + lux sensor for interior rooms — just 63 mm diameter and 5 mA bus consumption. For larger detection areas or outdoor IP54 applications, step up to the M/WS05.1 Wall Mount Outdoor Microwave Sensor. For full-room presence with humidity, consider HDL's M/SIS05.1 Presence Sensor (Φ12 m PIR range).
