Abstract:
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.
