I have a FEZ Spider mainboard and a PIR Motion tracker module (http://www.ghielectronics.com/catalog/product/357) attached to it.
What im trying to do, is to place it in a quiet room - and when i walk in to it - i want it to respond to that event.
When i run it, the event and the event handler below seems to fire randomly (like it doesnt matter if i stand in front of it and make movements).
void motion_Sensor_Motion_Sensed(Motion_Sensor sender, Motion_Sensor.Motion_SensorState state)
I have tried to adjust the two screws on the module, as described here for time delay and distance (http://www.elecfreaks.com/398.html) but i cant really make it fire the event when a human enters the room (it just fires randomly it seems)
I have attached some images of the sensor.
Is it faulty hardware? Does anyone know how to best adjust it?
