Literature Review Of Smart Irrigation System

Pressure system involves the use of drip irrigation and sprinklers but in gravitational system furrows and canals are utilized. Irrigation systems are grouped into two major categories namely pressure and gravitational. Keywords: Network, Microcontroller, Conservation, Global system for mobile communication. New technologies help in increasing productivity with use of less manpower as well as conservation of water in the process. Using DTMF 8870 IC will act as an interface between the user and the system as it is a receiver which links the GSM network, the microcontroller pic16f73 contains the software which states the conditions of the system which can be displayed in a liquid crystal display and transmitted via mobile phone to the dual tone multiple frequency receiver which is part of the control system in the farm.

Since PCB making is a big process and involves a number of machineries which are expensive and was therefore outsourced. Protel or workbench schematic software is used for designing the circuit diagram for this project and express prefabricated circuit board (PCB) software is used for designing. This project used some of the softwares like basic language for programming the application software to the microcontroller and visual basic for interfacing the hardware and mobile phone. The design portion involves mainly a global system for mobile communication and a control circuitry with a microcontroller. This project is based on moisture sensor used to measure humidity content in the soil.
