However, the market price of these gadgets is rather costly, making them difficult to obtain for farmers. As a result, our team created the " Automatic Monitoring and Control System in Agriculture based on IoT" to meet the need to monitor the environmental parameters of the garden, ensuring that the garden is always in the best condition, as well as cost more affordable to farmers and tree enthusiasts. The system has the following capabilities that can be controlled via a smartphone app. Sensor data, device status, and camera images will be captured and continuously updated to the App.
The system has two operating modes: manual and automatic. In MANUAL mode, users can actively control devices, turn them on and off as needed, regardless of environmental conditions, such as watering plants, turning on lights, turning fans on and off, and most importantly, selecting the sowing place and having the app irrigate automatically. In AUTO mode, if the user activates the water pump or seeding button, the system will automatically water or sow seeds at all pre-programmed positions. In addition, the system also allows users to set temperature and humidity limits and from there the devices will operate based on environmental parameters.
In this project, we tackle this problem by collecting data inside the greenhouse using ESP 32 and ESP 32 CAM, sensors, and actuators, signal processing from the sensors using programming, and controlling the actuator to keep the garden in the proper condition. After that, the farmer can get real-time data on the smartphone. The operating model is relatively stable, the operations on the application are easy, and the online image can be observed through the Camera. xii Chapter 1: INTRODUCTION 1.
PROBLEM STATEMENT According to estimation, world population could reach to 9,8 billion in 2050, it would be 25% more than it is at the moment. Urbanization would be increasing in tendency significantly in 2050, nearly 70% of world population are expected to be urbanize (compared to 49%). Agricultural productivity must double by 2050 to support this big metropolitan population [2]. Crop production will become equally vital to industry, not only for food but crops such as cotton and rubber are also essential to the economies of many countries.
These demands place a further strain on already restricted agricultural resources. Internet of Things (IoT) is an important topic at the moment and the future of all thing and it is now changing life of everyone by doing everything smarter. Internet of Things is also known as a vast network in which any computer or practically anything with an IP address is linked to the internet or to another in order to automate operations or minimize human interaction smartphones, lights, watches, machine producing, cars, etc are some examples.
