The paper works on the principle of DTMF tone command so received from any phone to remotely switch any electrical load such as
agricultural pump, domestic and industrial loads etc. In industries, the loads are spread over a large area and thus, operating these
loads is a very tiresome and difficult task. In agricultural fields also, pumps and other loads are connected over a large area and hence
it is difficult for the farmer to operate all the loads and similarly for house hold loads. Keeping these problems in mind, the proposed
system has been designed which uses DTMF technology to control the loads remotely.
