Smart irrigation and soil component test
MetadataShow full item record
The aim of the projects to make an embedded system which will provide all the necessary information needed for the production of various crops in an efficient way making the whole process automatic, cost effective , eco friendly and attaining all other environmental concern. It will also provide the amount of soil nutrients and following to that measurement, an apps database will help to find out the amount of fertilizer to be used in particular field. A soil moisture sensor with low-cost was modeled, simulated and tested for achieving accurate and reliable measurements. A high-performance ph probe is calibrated with linearity of the ph scale. Accuracy maintained by scaling it with the help of linear regression and curve fitting in MATLAB. Combining all these things the total irrigation system made automated with a time to time state. A device is used to detect the color changes of soil solution (which is found with the help of reagents provided by Mymensingh Agricultural University) through image processing to verify the amount of soil nutrients. The aim is to improve farm productivity and input use efficiency of water and other nutrients needed for the soil. This system presents the design and development of Irrigation controller System built with Arduino controlled board. The system consists of microcontroller, peripherals including RTC, LCD and driver circuit relay to switch on/off a motor. The soil component testing device is built with camera for image processing with on board switching and status display. An android app is optionally built to make the overall system more smart, user friendly and reliable. The whole system will take the agriculture sector of Bangladesh into a new height where the process will be automated as well as cost effective and environment friendly.
