This system not only solved the cost of the system but also provides necessary data that is required to know about the field area of the farmer. This paper also includes the purposed concept of irrigation systems in which this paper publish how important to be automated irrigation is needed to farmers can achieve their goal and helps to reduce the burden from them.

Water supply for plants, Trees, Flowers, and Farming fields is called an irrigation system. Irrigation needs continuous monitoring of the water level and soil moisture of plants. In Modern days costing of every item has increased due to world order, pandemic, recession, disturbed supply chain, chip shortage [1], and these busy schedules people don't have sufficient time to monitor every single plant in the field, but there are hopes on IoT technologies [2] that can reduce the burden that generated due lack of time and money. In India, the country depends on farming for a huge amount of GDP contribution and at least 70% of people [3] depend on farming for their living. The country not only produce food for itself but also to export other needy countries and donation, charities in poor countries through International organizations but remain in this position country have to enhance productivity with the help of technology. For high- quality products and to reduce the burden from the farmer needs to have a good irrigation system [4] because for high productivity water supply is the most important thing in farming. Irrigation needs to start water pump on time if soil moisture reduces this concept [5] is used to make a system using Internet of Things technology. The project aims to make a low-cost irrigation system using IoT technologies. It is necessary to monitor the environmental conditions in and around the field and soil moisture. The Internet of Things (IoT) has the potential to make the device for irrigation at a very low cost with the number of sensors [6] to collect data from the soil, weather, light intensity, raindrop, etc. The parameters that have to be properly monitored are soil characteristics, weather conditions, moisture, temperature, etc. This can be possible by using IOT technology with sensors and actuators that can sense the field condition and perform the certain task accordingly sensors are used to monitor and collect information about the field conditions, and those data are collected to make a low- cost irrigation system. 2. PRELIMINARIES For the implementation model, it needs to follow some steps one by one. Step 1 Firstly one breadboard is required to arrange all the equipment into one system. The types of equipment are sensors like Soil moisture sensor, DHT11 sensor, LDR sensor, Water sensor, Actuator like Relay module is needed to perform the task, microcontroller board NodeMCU and connecting wires with the USB cable to connect the system to the computer and motor pump for irrigation. Connection of all the sensors to the breadboard as per circuit diagram. Fig 2.1 Step 2 Create a connection of sensors, and actuator, on the breadboard to the NodeMCU with connecting wires called model. That model is now connected to the computer
