You can use your control panel easily even with very sensitive touchs by using this module which has 3 keys.
The Q Touch Sensor is a high sensitivity and high noise immunity touch input device.It is based on Atmel AT42QT1070. The AT42QT1070 modulates its bursts in a spread-spectrum fashion in order to heavily suppress the effects of external noise, and to suppress RF emissions. The QT1070 uses a dual-pulse method of acquisition. This provides greater noise immunity and eliminates the need for external sampling capacitors, allowing touch sensing using a single pin.
