[Tinyos-help] Need Help

depends on what you are trying to do.

1) let say if you want to track a person's location, you can apply 
location tracking algorithm using native RSSI value from the CC2420 
radio or by detecting radio signal strength difference, you can say that 
an object go pass two Tmotes.

2) if you want to detect something moved in front of a sensor, maybe the 
infrad sensor is enough. Lookup proximity sensors.

 From a research point of view, detecting RF field strength different is 
an interesting research topic (BUT some WSN research groups have done 
the same thing using RFID) :-)
