Device Control Using Intelligent Switch

Sreenivas Rao MV, Basavanna M

Intelligent switch is capacitive touch sensor which senses the touch. This type of switches takes body capacitance as a input in order to turn ON or OFF the devices which is connected to it and also the regulation of it. The devices controlled are bulb, fan, motor and other electronic appliances. This touch switches are needed in order to overcome the disadvantages of mechanical switches like wear and tare, limited operations, sparks etc. The capacitive touch sense pad which consists of one or more sense buttons. When the person touches the touch pad it takes the body capacitance and that analog signal is converted to digital signal in order to make compatible for the MSP430G2553 microcontroller to operate. This microcontroller contains pin oscillator and PWM which is used to turn ON or OFF and regulation of the particular devices respectively. Finally, the capacitive touch sensor are used to replace the mechanical switches thus providing high reliability, shock proof, trendy looks etc. The regulation of the devices which is connected to these switches can also be done using the same switches. Here regulation means light intensity control in the in bulb, speed control in the case of motor etc. Thus it reduces the power consumption and improves the quality of life.
