Using Microcontroller Based Digital Portable Soil Testing Device (“Matir Pran”) for Agricultural Sector Development

Abstract

The major economic sector in Bangladesh is agriculture, which contributes 19.6% of the nation's GDP and employs 63% of the residents. The agricultural products feature like growth, quality dependent on the soil condition. Now a day’s most of the farmer’s family in Bangladesh uses smart phone. Based on this availability of smart devices and huge potentiality of uses of the devices, this project and study have been done for finding the common most useful two features of soil like measuring the pH level and testing the moisture of soil instantly, which usually reported after a long-time traditional process of analysis. These android-based apps incorporated in the smart device, which help the farmer to plant crops based on the testing parameters - pH level and moisture displayed in the screen of the devices. After testing android apps suggests the farmers- which types crops they can plant in this field, it can also suggest the way of increasing and decreasing the pH level. Arduino Nano, OLED display, pH sensor, moisture sensor are the main hardware and XML, material design (for front end) and JAVA, SQLite database, (for back end) are the software uses in the project.
