Parallax X-Band Motion Detector

The Parallax X-Band Motion Detector uses the well proven technology behind security sensors to detect motion in its field of view. What makes is particularly useful is it can detect motion through walls and windows. Cool! And it can do this over a range of approximately 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)
