Farmers are currently dealing with a severe drought-like situation all year long. This paper's primary goal is to offer a system that enables automatic irrigation, saving farmers time, money, and energy. This paper describes an automatic irrigation system based on Arduino. On the field, the moisture sensors will be deployed. These sensors will detect any change in the concentration of water and send an interrupt signal to the microcontroller. The humidity sensor is connected through a comparator to the internal ports of the microcontroller. When the environment’s temperature and humidity fluctuate, the sensors detect it and send an interrupt signal to the microcontroller, which activates the motor. Attached is a moisture sensor, which measures the soil’s water content. When it comes to travelers, automatic irrigation systems are quite useful. Automatic irrigation systems have the potential to be highly economical and water-efficient if they are correctly designed and coded. Water is applied to plants automatically by means of an irrigation system that requires no human input. A network of pipes or hoses is usually used to transport water to plants, sensors are used to assess soil moisture levels, and a controller is used to analyze the data and initiate water delivery. The automation of watering chores using water irrigation systems is revolutionizing farming and agriculture. These devices guarantee that plants receive the right amount of moisture while saving time and water. They encourage healthier plants and lessen their impact on the environment by automating the watering procedure (Parameswaran and Sivaprasath in Int J Eng Sci Comput 6, 2016; Chavan and Karande in Int J Emerg Technol Comput Sci & Electron (IJETCSE) 20:203–206, 2016; Balaji and Sudha in Int J Adv Eng Glob Technol 04:1567–1570, 2016).
