Now a days in market, the sensors used in agricultural sectors are not integrated together, they are individually available. So, we have developed a system where these sensors are integrated, and all the data is shown on a Mobile App. Some of the sensors used in our system are in house designed and fabricated. The system provided by us is more sensitive than some of the readymade sensors available in the market leading in precise values of the parameters of the agricultural land. And, the idea is to develop a multilingual mobile application which will communicate with on field hardware to show real-time data to user. The application will also show the trends and crop suggestions to farmer. With Animal intrusion detection system, farmers will be able to protect their crops from harm caused by wild animals. In the further part of the paper, the components and the software systems are discussed which were used in the development of the system, and at last, the challenges and future scope of “Smart Agriculture System”.
