Product Features Applications • The Touch Sensor is a capacitive touch sensor and can detect a touch through plastic, glass, or paper. • We recommend a material thickness of up to 1/2”. • The sensor can also be attached to metallic objects to allow for a larger touch pad Connections Designed to connect to a: • 1018 - PhidgetInterfaceKit 8/8/8 • 1019 - PhidgetInterfaceKit 8/8/8 w/6 Port Hub • 1070 - PhidgetSBC • 1202 or 1203 - PhidgetTextLCD Type of Measurement The sensor uses ratiometric measurement.
Getting Started Checking the Contents You should have received: • A 1129 Touch Sensor Board • A Sensor Cable In order to test your new Phidget you will also need: • A PhidgetInterfaceKit 8/8/8 • A USB Cable Connecting all the pieces 1. Connect the Touch Sensor to the Analog input 6 on the PhidgetInterfaceKit 8/8/8 board using the sensor cable 2. Connect the InterfaceKit 8/8/8 to your PC using a USB cable.
Double Click on the icon to activate the Phidget Control Panel and make sure that the Phidget InterfaceKit 8/8/8 is properly attached to your PC. 1. Double Click on Phidget InterfaceKit 8/8/8 in the Phidget Control Panel to bring up InterfaceKit-full and check that the box labelled Attached contains the word True. 2. Make sure that the Ratiometric box is Ticked. 3. Touch the back of the Sensor Board.
Testing Using Mac OS X • Click on System Preferences >> Phidgets (under Other) to activate the Preference Pane • Make sure that the Phidget InterfaceKit 8/8/8 is properly attached. • Double Click on Phidget InterfaceKit 8/8/8 in the Phidget Preference Pane to bring up the InterfaceKit-Full example. This example will function in a similar way as the Windows version, but note that it does not include an Advanced Sensor Display.
Technical Information The Touch Sensor changes value from 0 to 1000 when it is touched. More specifically, this sensor is actually a capacitive change sensor. When the capacitance changes the sensor reports a thousand. If the sensor remains at 1000 for longer than 60 seconds, it will recalibrate back down to zero, regardless if the sensor is still being touched. This recalibration can also be done manually by unplugging and plugging the sensor back into the Interface kit.
