Abstract: An automated irrigation system is proposed to be developed to optimize water use for agricultural crops. The system has a distributed wireless network of soil-moisture and temperature sensors placed in the root zone of the plants. In addition, a gateway unit handles sensor information, triggers actuators, and transmits data to a web application. An algorithm was developed with threshold values of temperature and soil moisture that was programmed into a microcontroller-based gateway to control water quantity. The system was powered by photovoltaic panels and had a duplex communication link based on a cellular-Internet interface that allowed for data inspection and irrigation scheduling to be programmed through a web page. The automated system was tested in a sage crop field for 136 days and water savings of up to 90% compared with traditional irrigation practices of the agricultural zone were achieved. Three replicas of the automated system have been used successfully in other places for 18 months. Because of its energy autonomy and low cost, the system has the potential to be useful in water limited geographically isolated areas. EXISTING SYSTEM: Traditional & GSM Based Irrigation System: The existing system about the farming based on irrigation is Traditional and GSM Based irrigation system in which the water pumping motor can be controlled by GSM by sending SMS thanks R.Ashok kumar MAASTECH 89.

1. Automated Irrigation System Using a Wireless Sensor Network and
GSM Module
Abstract:
An automated irrigation system is proposed to be developed to optimize water use for
agricultural crops. The system has a distributed wireless network of soil-moisture and
temperature sensors placed in the root zone of the plants. In addition, a gateway unit handles
sensor information, triggers actuators, and transmits data to a web application. An algorithm was
developed with threshold values of temperature and soil moisture that was programmed into a
microcontroller-based gateway to control water quantity. The system was powered by
photovoltaic panels and had a duplex communication link based on a cellular-Internet interface
that allowed for data inspection and irrigation scheduling to be programmed through a web page.
The automated system was tested in a sage crop field for 136 days and water savings of up to
90% compared with traditional irrigation practices of the agricultural zone were achieved. Three
replicas of the automated system have been used successfully in other places for 18 months.
Because of its energy autonomy and low cost, the system has the potential to be useful in water
limited geographically isolated areas.
EXISTING SYSTEM:
Traditional & GSM Based Irrigation System:
The existing system about the farming based on irrigation is Traditional and GSM Based
irrigation system in which the water pumping motor can be controlled by GSM by sending SMS.
DRAWBACK OF EXISTING SYSTEM:
1. Non effective as no real time monitoring available.
2. No Control in the case of emergency like draught or high temperature is possible locally
or globally.
PROPOSED SYSTEM:
Wireless Sensor Network and GSM Based Irrigation System
ADVANTAGES OF PROPOSED SYSTEM:
1.
2.
3.
4.
Highly accurate and reliable system.
RF and GSM control & Monitoring.
Global monitoring & control using Internet with GSM Modem.
Local monitoring & control using Internet with RF Module.
