As we can see, only certain devices, like PCs and mobile phones, are connected to the internet in today's world. The internet and the internet of things have completely taken over the world in recent times. Every human being relies on the internet for essential needs. The physical object network is known as the Internet of Things (IOT). It simply refers to monitoring a machine or physical device, or it can refer to the interconnection of physical devices that are embedded with electronics, sensors, software, and network connectivity to enable them to achieve greater value and services by exchanging data with the manufacturer. The majority of people rely on agriculture. Water scarcity is the primary issue in agriculture. Water is wasted because the resource is not utilized effectively. This irrigation procedure can be automated to overcome it. In this field, using the Internet of Things will help cut down on water waste. Using sensors, the temperature, humidity, and light can be measured, and subsequent processing can be based on the results. The Internet of Things (IoT) enables objects to be sensed or controlled remotely across the network infrastructure. We propose a system that will use a variety of sensors to record every detail about the soil and the temperature. The outcome reduces human intervention and improves accuracy, efficiency, and economic benefits. We will discuss fundamental and significant IOT concepts and their future scope in this paper. This paper provides brief information about IOT and examines the need for IOT in everyday life for various applications. The Internet of Things (IoT) significantly contributes to revolutionary farming practices. Therefore, our goal is to demonstrate IOT through an automated watering system. The soil's approximate moisture content is monitored and maintained by an automatic watering system. The control unit is implemented with the help of an Arduino UNO microcontroller. The setup makes use of a temperature, moisture, and humidity sensor to approximate the soil's temperature, moisture, and humidity. The system can use the right amount of water thanks to this value, preventing over- or under-irrigation.
