As we see many of the recent powerful hardware coming to market, the combination of these touch sensors along with the high-performance CPU exponentially improves the efficiency of the final product. The touch sensor detects that change and will make the output of that channel go to low voltage which can be regarded as zero. The sensor detect any motion in its permissible range and triggers the alarm. When the switch pad is left untouched, then the potential difference between the emitter and the collector will be 12V and the potential difference between the emitter and the base will be zero (this I admit is debatable), since the base is not connected anywhere, which means the difference of potential between the base and the collector is 12V in a direction that reverse biases the collector-base junction. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. The Capacitive touch sensors are very popular since they are more robust, durable, and user friendly. When any physical medium comes in contact with the touch surface.
