The X-Band Motion Detector’s sensor is a common component in security systems and automatic door openers and can detect movements within a room, yard, or even on the other side of a wall. The X-Band Motion Detector operates in the X-band frequency, at 10.525 GHz and indicates detected movements with oscillations in its high/low output. Sensitivity is manually adjustable with a potentiometer, offering direct line of sight detection from roughly 8 to slightly over 30 ft (~2.4 to 9+ m).
Key Features:
Trim potentiometer for manually adjustable sensitivity
4-Pin SIP header for breadboard or through-hole prototyping
Built-in series resistor for compatibility with the Propeller microcontroller and other 3.3 V devices
Plated test point hole for monitoring pre-comparator signal
Application Ideas:
Security systems
Automatic door openers
Automatic lighting
Nuisance animal deterrence
