AccessTouchTM
Touch sensitive keyed access controller
Summary
AccessTouch is an integrated combination key
access controller featuring tough-sensitive keys for
vandal-proof operation. An accompanying design
blueprint is available for a complete low cost,
access control product.
AccessTouch uses capacitive touch sensing
technology. The PCB keyboard shown can be
overlaid
by
a
non-metallic
covering.
It
automatically
calculates
signal
averages
to
compensate for track capacitance, water splashes,
etc. A buzzer output provides audio feedback as
buttons are pressed.
AccessTouch is firmware for the PIC16F631
microcontroller and is available as a pre-
programmed chip from electronics distributors or
as a firmware download from www.hexwax.com.
User Operation
When the correct code is entered, the door release
output is activated for a fixed time delay. The
sequence of keys pressed prior to entering the
code is unimportant.
To change the access code, an electrical switch is
closed and the new code is entered twice. LEDs
indicate ‘Open’, ‘Closed’ and ‘Set Code’ states. All
LEDs turn off when the device enters a sleep
state.
Features
Tiny volume BOM cost
Vandal-proof design, no parts need to be
physically exposed
Codes may be up to 8 digits
Audio feedback on touch press
Safe Controller mode available
20-pin SSOP package
