This document summarizes a B.Tech final project presentation by Sudama Maharana and Akhilesh Choudhury on developing an agricultural soil tester. The project uses sensors to measure pH, moisture, electrical conductivity, and temperature of soil. The readings are processed by a microcontroller and displayed on an LCD screen. The presentation covers the objectives, hardware requirements, sensor types, microcontroller, LCD interface, hardware setup, output steps, advantages and disadvantages, and future plans. The soil tester is intended to help farmers test soil parameters and determine appropriate crops and fertilizers.

FUTURE PLANNING
 We have the Ph interfacing circuit. So, we can easily interfacing
the pH sensor with Arduino microcontroller.
 As Arduino microcontroller has 6 analog input ports, so we can
interface 3 more sensors.
 We can interface GLCD screen to show a huge amount of data.
 We can store the Data in Data Base.
Our future planning are,
