Put your finger on the Phidgets circular touch, and it feeds the data back to your PC!

Description [Hide]

The PhidgetCircularTouch detects changes in the capacitance between the on-board electrodes and the object making contact. The side of the circuit board opposite the connector and components is the side intended for contact.

It can be mounted behind a sheet of glass or plastic; The recommended thickness is 1/8 inch. Use Silicon adhesive when attaching the Phidget to the material; standing the PhidgetCircularTouch off or creating space between the separation material and the Phidget can cause false-triggering to occur. Materials thicker than 1/8” may work, but will require a larger surface area of contact to ensure proper triggering (i.e.: two fingers instead of one).

Sliding a finger along the touch sensor varies the Analog Input 0 value from 0 to 1000 in approximately 125 discrete steps. When the finger is removed, the final measured value is retained. Two Digital Inputs are used to convey additional information: Digital Input 0 is True when contact is made with the Phidget, and Digital Input 1 is True when a finger or object comes in close proximity to the board. The Analog Input value is valid when both Digital Inputs are true.

Comes packaged with:

  • A 120cm Custom USB Cable
  • A mounting hardware kit
  • Item 1610
