X-Band Motion Detector (Parallax 32213)

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.

The X-Band Motion Detector's sensor 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. 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).

Features:

• 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
• 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

Key Specifications:

• 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)
