X-Band Motion Detector

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.
   

Details:

• Operation frequency of 10.525 GHz.
• Able to detect motion through walls and windows.
• More immune to false triggers than passive infrared motion sensors.
• Active-high enable pin with internal pull-up resistor.
• Power supply requirements: regulated 5 VDC, 8 mA.
• Communication: High (3.9 V) / low (0 V) signal oscillates with motion.
• Dimensions: 1.8 x 1.75 x 0.75 in (46 x 45 x 19 mm).
• Operating temp range: +32 to +131 °F (0 to +55 °C).
