The Pololu IR beacon is a compact board that is used in pairs to allow robots to locate each other.
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.
This sensor measures 10 full turns, 3600 degrees of rotation goodness.
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 IESF-R-5 Pressure Sensor is a variable resistance sensor where the output resistance is proportional to the force applied to the bulb.
