Four spindles on the trackball have a tiny circular magnet the end; each of these are paired with an SMD hall effect sensor, which are used to measure up, down, left and right movements of the trackball.
The MEAS Vibration sensor is flexible and durable.
Use this 60cm/24" sensor cable to plug in your Phidgets sensor to the Interface Kit 8/8/8.
A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. COOL! Add it to your clothes - ideal for interfacing with LilyPad Arduino!
The Phidget 8/8/8 Interface Kit uses the very common USB interface to connect 8 analog inputs, 8 digital inputs and 8 digital outputs to your Phidgets sensor network.
The Phidget Force Sensor works with the Phidget 8/8/8, measuring up to 3 Kg of force.
