PIR Sensor Issue

So I'm a complete newbie and I decided to follow Motion Activated LEDs : 8 Steps - Instructables to make a led motion activated light but for some reason my Leds are lighting up like the motion sensor is telling them to which would be great IF there was motion for the sensor to be picking up.

I think that I may have goofed on which sensor Im using the one he used was PIR Sensor with LED Signal - Parallax and the one I have is PIR Motion Sensor (JST) - SEN-13285 - SparkFun Electronics
Is there any way that I can adjust for this?
