- Standalone Capacitive Touch Sensors - vender: www.adafruit.com
I found these sensors some time ago and first used them on my Mini-ITX Tower project. On that project I used the “Standalone Momentary Capacitive Touch Sensor” for the power on switch and the Standalone Toggle Capacitive Touch Sensor for the lamp switch.
Today I am using the “Standalone 5-Pad Capacitive Touch Sensor Breakout - AT42QT1070” and wiring up a control panel with a touch power on, a lamp on and a lamp off and a reset; this will use 4 of the 5 sensor circuits. And because I prefer to not add electronics to motherboards, I am using relays to isolate the touch sensors from the motherboard logic.
Here is the 5-pad unit on my desk. I have a copper penny as a pad taped to a .187 inch thick ABS plastic plate and my finger is being sensed through the plate as evidenced by the lit LED.
These units are reasonably priced and Adafruit usually ships same or next day. I use US Postal Service and the shipping cost is very reasonable.
Good modding,
neil
