This document describes a DTMF-based system for controlling agricultural appliances and industrial equipment remotely. It introduces DTMF technology that allows devices to be operated using touch-tones from a phone. The system uses a DTMF decoder connected to relays, lights, motors, and other devices that can be turned on/off by dialing codes into a DTMF mobile phone. This automation saves resources, labor, and provides reliable remote control of equipment to improve agricultural and industrial operations.
