GY INTRODUCTION

AGRICULTURE SOIL TESTER:

Agriculture soil tester is a low cost hand held.

The device aim at reading parameters such as Moisture, pH, Electrical conductivity, temperature.

It will help farmer to test their soil and plan for appropriate crop, fertilizers.

GY ADVANTAGES & DISADVATAGES

• We cant Know about the chemical properties like nitrogen,

phosphors etc of soil.

Advantages of soil testers are :-

Disadvantages of soil testers are :-

• Monitors pH, moisture ,EC and Temperature.

•Able to Know where to Plant a crops.

GY 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,

GY CONCLUSION

We have analyzed the how Arduino microcontroller sense the different physcial parameters and give different outputs.

How crucial the parameters such as pH, Soil Moisture Electrical

Conductivity (EC),Temperature Etc. while planting the crop.
