Application of wireless technologies in agricultural pumps

Today, automation is preferred in every sector. Automated systems being more flexible to use, offers high accuracy and reliability in long term operations as compared to manual operated systems. Problems faced by farmers in the agricultural system are of great concern these days. This work is an attempt to implement automation for control of electrical motor or pump used in agriculture domain. The agriculture work by its nature is a field job, hence devices used are sparsely distributed. This makes it difficult for farmers to control and operate these devices in real time. With the emerging technologies, we have seen the advent of many wireless communication techniques, having lower operating cost along with interactive protocols. The system's operational range is scaled up by the use of the GSM communication system. This work suggested a method which utilizes the potential of low power, high speed microcontrollers by using widely accepted open source Android platform. The proposed model enables us to control the field devices over a wireless link which is GSM based and can read signals from sensors connected in the field and can send the sensed electrical parameters of the motor or pump to an Android device. A GUI (Graphical User Interface) is developed for Android device and successfully performed testing for switching ON and OFF of the motor or pump remotely. Also, provided a simple display of availability of power at remote locations.
