Wireless Sensor Network Based Remote Irrigation Control System and Automation Using DTMF Code

Agriculture is a source of livelihood of majority Indians and has great impact on the economy of the country. In dry areas or in case of inadequate rainfall, irrigation becomes difficult. So, it needs to be automated for proper yield and handled remotely for farmer safety. In this paper we suggest a Wireless sensor network and Embedded based technique of DTMF (Dual Tone Multiple Frequency) signaling to control water flow for sectored, sprinkler or drip section irrigation. This system will be very economical in terms of the hardware cost, power consumption and call charges. The proposed control system works on two principles one is wireless sensor network and another is of ´circuit switching´ instead of ´packet switching´ used by SMS controlled devices available currently in the market. In this paper, the complete installation process along with the circuit, designed and tested on a prototype environment, is explained.
