The PhidgetInterfaceKit 0/16/16 provides 16 digital Inputs/Outputs with hardware noise filtering and input tolerance up to 30V. This board comes with a 180cm Mini-USB cable and a hardware mounting kit (4 nuts and bolts, 4 plastic spacers).
The Voltage Sensor measures the differential voltage between the input terminals and outputs the difference proportionally. The maximum differential voltage that can be measured accurately is &plusmin;30V. This sensor comes with a 60cm sensor cable.
The high resolution HRLV-MaxSonar-EZ sensors are high performance ultrasonic sensors with noise rejection, improved automatic calibration, and factory calibrated beam patterns. These are the best sensors for indoor use, with virtually no dead zone and a resolution of 1 mm!!!
