I see that the PhidgetInterfaceKit 8/8/8 (ID: 1018_2) is compatible with the MaxBotix EZ-1 Sonar Sensor (ID: 1128_0). Is it also compatible with other MaxBotix sensors like EZ-2 and EZ-4 that are not available in your store?
I can confirm that the 1018 and other Phidgets with analog inputs or VINT ports will be compatible with any MaxBotix board from the LV-MaxSonar-EZ line. Any MaxBotix board with an analog output pin will be able to be read by Phidgets.
Of course, you'll need to read the datasheet to get a different formula to convert from voltage to distance.
