DTMF Based Controller for Efficiency Improvement of a PV Cell & Relay Operation Control

  title={DTMF Based Controller for Efficiency Improvement of a PV Cell \& Relay Operation Control},
  author={Roshan Ghosh},
The human mind always needs information of interest to control systems of his/her choice. In the age of highly advanced electronic systems many methods of remotely control systems have been developed, these methods have the problems such as the need for special devices and software to control the system. This paper suggests a method for control using the DTMF tone generated when the user pushes mobile phone keypad buttons or when connected to a remote mobile system. This DTMF based controller…
