== Software ==
You can download the Arduino sketch [[http://code.mios.com/git_public/mios/arduino-sensor.git/tree/HEAD:/VeraArduino/Arduino/libraries/Vera/examples/MotionSensor?js=1|here]].\\

This sensor sleeps most of the time. If interrupt on digital input occurs it wakes up and transmits change. 

== Wire things up ==

Follow the instructions in ConnectingRadioModule to connect radio module.

Connect the digital OUT of the motion sensor to digital input 3 of Arduino board. 
Connect VCC to +5V of the Arduino board. GND to GND.
Use the trimpot Sx on sensor to set sensitivity. Trimpot Tx tunes how long the sensor should be triggered (5sec min - 200sec max).

== Hardware - Purchase guide ==

To build this sensor you'll need one arduino + radio specified in the base kit found here:\\
