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.
overlaid
automatically
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
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.
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.
