- X-Band Motion Detector
The X-Band Motion Detector from Parallax 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!
This little board utilizes a Doppler radar sensor that operates in the X-band frequency at 10.525GHz, 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 8ft to slightly over 30ft (~2.4 to 9+ m).
- Power supply requirements: regulated 5VDC, 8mA
- Communication: High (3.9V) / low (0V) signal oscillates with motion
- Operation frequency of 10.525GHz
- Trim potentiometer on the back for manually adjustable sensitivity
- 4-Pin SIP header for breadboard or through-hole prototyping
- Dimensions: 1.83 x 1.87 x 0.69 in (46.5 x 47.5 x 17.6 mm)

Absolutely no output from this module.
Tried adjusting sensitivity, checking test point with oscilloscope and nothing. Disappointed.
