The problem pH Detector solves

It notifies the pH of the soil or the sample used. Then, it gets displayed on the GPS location tracker. By this method, the concerned authorities can take neccessary steps to get the soil into correct pH.

Challenges I ran into

Calibration of the pH probe was one of the major challenges, as one need to calculate the whole things. The pH probe sends in value in terms of Voltage. So, we need to convert the voltage value into simple pH value so that the authorities can understand it. So, using complex mathematics, we were able to calibrate the pH probe properly.
