Project DTMF (dual tone multi frequency) tone ordering concept so any phone works on remotely obtained from such agricultural pumps, domestic and industrial weight etc industries to switch any electrical load, loads are spread over a large area and thus, these weights to handle a very tedious and difficult task.
Also in the agriculture sector, pumps and other loads are connected over a large area and therefore it is difficult for the farmer House work and so all the weight to. Keeping these issues in mind, the proposed system which loads to control DTMF technology is designed.
A cell phone voice commands to get your audio output socket is a DTMF decoder system interfaced with. Get cell phone code to identify an instance of that key DTMF decoder and digital code which is equivalent to a microcontroller (8051 family) is fed to that frequency will change are converted to digital by using commands.
According to the commands that are sent from the sender's mobile, send a signal through a buffer microcontroller/ By turning off the relay will actuate the respective weight. These relay a relay driver IC are inspired by the microcontroller interfaced.
In addition this project by sending an SMS, GSM modem, where the load can be controlled can be enhanced by using. This system works to eliminate the need to answer the phone.
