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.
The Phidget 8/8/8 Interface Kit uses the USB interface to connect 8 analog inputs, 8 digital inputs and 8 digital outputs to your Phidgets sensor network.
The Parallax ColorPAL is a miniature color and light sensor which uses an RGB LED to detect and generate light for color sensing.
When the QTI sensor is over a dark surface, the reflectivity is very low; when the QTI is over a light surface, the reflectivity is very high and will cause a different reading from the sensor.
