Capacitive Touch Sensor Breakout Board – AT42QT1011

• Capacitive Touch Breakout
• Momentary capacitive touch button with easy-to-use digital I/O pins
• Output line value: High / Low
• Power source: 1.8V–5V

The Capacitive Touch Sensor Breakout Board – AT42QT1011 offers a single, momentary capacitive touch button with easy-to-use digital I/O pins. The AT42QT1011 is a dedicated, single-button capacitive sense chip. The chip handles monitoring a conductive area for touch. As long as a touch (e.g., from a finger) is detected, the AT42QT1011 keeps the output line high. Otherwise, the line is kept low.

You just need to provide a power source (1.8V–5V) and ground for the AT42QT1011 to work. Additionally, a PAD pin is available if you would like to create your own external electrode.
