Parallax Inc X-Band Motion Sensor Module

X-Band motion detector module

The X-Band Motion Detector operates in the X-band frequency of 10.525GHz 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 2.4 to 9m.

Operating frequency: 10.525GHz
Less prone to false triggers than passive infrared (PIR) 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 3.3V devices
Plated test point hole for monitoring pre-comparator signal
Power supply requirement: regulated 5Vdc @ 8mA
Communication: High (3.9V) / low (0V) signal oscillates with motion
Dimensions: 46 x 45 x 19mm
Operating temperature range: 0 to +55°C
