Accelerometer
These measure ( gasp ) acceleration. May be caused by gravity or the second derivative of position ( relative to an inertial frame ). Since acceleration is a vector to go the whole distace you need a 3 axis sensor, but often 1 or 2 D will do. Often the output is a voltage(s). Feed it to a microcontroller with an a to d converter, perhaps through an operational amplifier. Op amp

some are analog some use microcontroller interfaces LM34, LM35
Further Reading
- WSN:Sensors
- Interfacing with Hardware See the section on "Input" Writtern for the arduino but usefull just for the info on sensors.
- Welcome to the ITP Sensor Workshop Wiki. A whole wiki on sensors, looks good.
