Design and Development of Arduino Based Physical Parameter Analyzer for Unprivileged Region Agricultural System

Abstract

 Introducing scientific methods to the cultivation system is sorely needed in overpopulated
countries like Bangladesh. As the demand for food is rapidly increasing while the farming areas are
squeezing day by day. The cultivation system of our country follows the traditional harvesting process which
does not employ any scientific analysis of the agricultural sites. But proper measurement and analysis of
these parameters can magnificently improve the harvesting result. This article presents the design and
development method of Arduino based low-cost physical parameter analyzer which can be constructed easily
and used by the farmers of rural areas. The system was controlled with an Arduino microcontroller which
can receive analog signals from different sensors and show the measurement results in digital form through a
liquid crystal display. DHT11 sensor is one kind of capacitor that has humidity holding substrate as
dielectric which was interfaced with the microcontroller to measure both the relative humidity and
temperature. While FC-28 soil moisture sensor measures the relative soil moisture by sensing electrical
resistance of the soil. A JXCT-pH sensor was also incorporated to evaluate the pH level of the soil. The
developed system is also capable of continuously monitoring an agricultural site and taking some emergency
action if the standard value of the physical parameters deviates drastically .
