Creating Custom Analog and Digital Devices
While the Interface Kit and its off the shelf devices will satisfy almost all needs, the occasional developer
may want to include a sensor, switch or output type that is not available through Phidgets. Fortunately,
this is still very easy to do, and only a rudimentary knowledge of electronics is needed. Read on!
Using the Analog Inputs
The Analog Input can measure a voltage between 0V and
5V. The analog measurement is represented in the
software as a value between 0 and 1024, so a sensor
value of 1 unit represents a voltage of approximately 5
millivolts.
Each analog input uses a 3-pin, 0.100 inch pitch locking
connector. Pictured here is a plug with the connections
labeled. If this is wired backwards, damage to your sensor
may result. The Interface Kit pr 5 VDC, ground,
and an analog input with a range of 0 to 5V.
We offer an expanding line of packaged sensors that can
be plugged directly into the analog inputs. Experienced
users are encouraged to interface their own sensors.
The connector is manufactured by Molex, part number
50-57-9403 and 16-02-0102 for the wire crimp insert, and
is available from many sources including
www.DigiKey.com (Digi-Key part numbers WM2901-ND
and WM2510-ND). If you want to create your own sensor
boards than you can use one of the following Molex connectors on the circuit board: 70543-0002, 70553-
0002, 70553-0037, 15-91-2035 (Digi-Key part numbers: WM4801-ND, WM4901-ND, WM4925-ND,
WM1341-ND).
