The MCU respectively supplies two AC signals at two outputs thereof to two inputs of the flip-flop. The flip-flop outputs a first type output signal at the output thereof when the sensor not being touched. When being touched, the sensor receives electricity signals from an object, and causes a delay of an AC signal to be inputted to the input of the flip-flop to which the sensor is connected, the delay of the AC signal to be inputted to the input of the flip-flop further causes the flip-flop to output a second type output signal at a output thereof. The MCU detects a change of the output signals of the flip-flop from the first type output signal to the second type output signal and accordingly identifies a touch on the sensor.
