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) :-)

Hi,
In my academic project I want deploy a WSN to track a moving object.
Please anybody can tell me which sensors are useful to track a moving
object.
I have tested easysen's SBT80 sensor , but still I am not able to
understand the output of the program ListenSBT80vs.java which is
available on easysen website.
Also if anybody knows any other sensors please tell me.
Is there any open source code or tutor is available for this project?
Please reply as soon as possible,
Thanks in anticipation
