X-Band Motion Detector (#32213)
The X-Band Motion Detector is a common ingredient in security systems and automatic door openers,
and can detect movements in a room, yard, or even on the other side of a wall. It’s a Doppler radar
sensor that operates in the X-band frequency at 10.525 GHz, and indicates movements with oscillations
in its high/low output. Sensitivity is manually adjustable with a potentiometer on the back of the device,
offering direct line of sight detection from roughly 8 to slightly over 30 ft (~2.4 to 9+ m).
