Abstract
The yield of agriculture primarily depends on the soil moisture, soil fertility and the use of suitable fertilizers. The method of manually measuring the soil nutrients is inaccurate in the current scenario due to laps between soil samples collected at the field and measuring in the laboratory. IoT has made changes in so many fields to monitor the data remotely despite of existing wireless technologies like Zigbee, GSM, etc. In this work an effort is made to collect the data related to various soil nutrients from agriculture filed using multiple sensors. Once the data is monitored and collected at the control center helps to apply a machine algorithms to take the appropriate decision for an efficient crop yield. In the proposed system, the sensors connected to the node at the field measures the macro nutrients of the soil, temperature and humidity of the soil. The nutrition majorly required for the growth of the plant is nitrogen (N), potassium (K), and phosphorous (P) amount present in the soil. In this work a microcontroller with WiFi is used to interface various sensors and display the measured value in the LCD. This application will provide a user interface to monitor the fertilizers, irrigation and humidity control.
