IoT with sensor networks provides a new device to interact and observe the real-time data in physical world 4 provided with automation and decision making process. The system has capability of managing all types of issues in agriculture like animal control, quality management, supply-chain management and so on. 2.RELATED WORK Zhao et.al 1, proposed the integration of IoT (internet of Things) technology to real-time production of agriculture crops with remote monitoring and wireless communication using internet is proposed, a management system of information is also designed to handle the crops data for research purpose. Jayaraman P., et.al 13 presented the analysis by identifying the needs for agriculture based on the constraints or parameters like weather forecasting, crops farming, rural development, and market identification, relevant to the IoT perspectives and contribution of IoT towards poverty reduction. The challenges of 5G technology is also discussed. 3.PROPOSED ARCHITECTURE In this section an Architecture is proposed as shown Figure 1 for smart Agriculture using internet of things (IoT) which provides numerous benefits such as effective and efficient management of resources, knowledge development, intelligent management, monitoring, etc., The architecture 18-25 is divided into three layers namely: a. Physical Layer b. IoT Layer c. Com-op Layer - Physical layer The physical layer is a layer of automation to control the smart agriculture system.
