Soil analysis is essential in the process of agriculture. Various parameters can be derived from a soil sample. Some of them are moisture, NPK, fertility, PH value. The process of testing the sample at the laboratory and getting the report is tedious. This issue can be fixed by designing a rover system which can provide instant results with the help of integrated necessary microprocessors and sensors. Components includes rover, ultrasonic sensor, soil moisture sensor, temperature sensor, esp-32 camera. The measured values are then displayed to the user. The process of measuring and display of values occurs with the help of necessary arduino codes. The main objective is to notify the farmer/user regarding the parameters mentioned above to take actions accordingly. The interfaced camera is used for surveillance purposes.
