The presence detector is one of the most important sensors in any type of project. Thanks to its reliable detection of presence and motion, it forms the basis for the automation of important functions such as lighting, including constant light control, alarm, music, heating, ventilation or cooling and much more. This way you can easily solve complex tasks.

• Reliably detects movement and presence through infrared and acoustic sensors (acoustic sensor for Air variant only with solid power supply)
• High detection range with a detection angle of 360°; horizontal and 110°; vertical (results in 8m detection diameter with 3m ceiling height or 18m detection diameter with 10m ceiling height)
• Integrated brightness sensor (measuring range 0 ... 83000lx)
• Adjustable threshold value for acoustic sensor (with fixed power supply) for presence detection
• Adjustable threshold value for acoustic sensor (with fixed power supply) for alarm
• Simple limitation of the detection range by means of a sticker for the Fresnel lens

The Presence Detector Tree (100422, 100423) replaces the Motion Detector Tree (100223, 100224) - the Presence Detector Air (100420, 100421) replaces the Motion Detector Air (100190, 100192).
