Dual-tone multi-frequency beep tone toll-free automation in agriculture

This technical paper aims at bringing about a huge development in this domestic and agriculture sectors to protect the farmer's interest thereby ensuring the overall growth of this country's economy. The topic is all about introducing a toll-free automation system for farmers who are considered to be the lifeline of India. Automation plays an important role in every field of work and segment of human life in helping the human beings to improve their functioning. Dual-Tone Multi-Frequencies has numerous applications and utilization in a broader perspective. The usage of DTMF touch tones by customer service has increasingly gained its importance and attention in the field of automation albeit it is not free of cost. Considering the poor economical background and condition of majority of Indian farmers, the automation system should be so designed to save their money in a cost effective manner as a onetime investment device. To put it in a nutshell the technicality involved in this project is that DTMF beep ringtone is set as a ringtone in a mobile phone rather than its being used in any distant automation system. The function of DTMF Decoder is to decode DTMF tone in binary numbers that would be received through a missed call. Thus the code generated in the previous step activates the microcontroller that would trigger the relays to operate appropriate appliance that was intended. The whole aim of this project is to design and install a high secured distant controlled toll-free automation system that would empower the farmers to take care of the entire needs in one stroke in their day-to-day agriculture activity.
