World’s Smallest Presence Detector- IR Quattro Micro

IR Quattro Micro Ultra Small Presence Detectors is the World’s Smallest Presence Detector at 43mm diameter – the size of a Coin. Required by planners and architect, its small size and the low profile design make it perfect for application where disturbing installation on the ceiling are to be avoided. Available in both KNX & DALI Versions along with a smart phone app.

The size of the micro-precision lens is just 15 X 15 mm. And its performance is nevertheless stunning. The 360° infrared presence detector detects 36 m². And the IP65 classification lets you install it in rooms that are subject to moisture.

What more, this state of the art Presence Detector comes bundled with a smartphone app. STEINEL sensors and sensor-switched lights are very easy to control via remote control and the associated app. For this, a smartphone or tablet is placed on the Smart Remote and connected via Bluetooth. An infrared interface permits communication with the sensors and lights. It doesn’t get any smarter than that!
