Abstract
The efficient use of water is crucial for achieving sustainability of agriculture, especially in rural regions, where the usual methods of irrigation lead to unnecessary water consumption and excessive labor input. This paper discusses an IoT-enabled smart irrigation and water-efficient rural system based on an ESP32 microcontroller that automatically irrigates the farmland and remotely monitors the process. The proposed system uses soil moisture, temperature, humidity, water level, and rain sensing to continuously monitor the environmental conditions. The ESP32 microcontroller analyzes the data from the sensors and automatically manages the water pump by controlling the relay according to the pre-specified soil moisture value, thus avoiding unnecessary and excessive irrigation. The Wi-Fi enabled IoT platform with the Internet connection is used to monitor the sensor values and the state of the water pump with the help of Blynk and ThingSpeak mobile applications. The calibration and testing of the sensors in a laboratory using the garden soil was conducted to examine the work of the proposed system.
Rapid urbanization and the declining availability of arable land have increased the need for sustainable and efficient farming practices in urban areas. Although urban farming offers significant potential, it faces several challenges, including unreliable water supply, inefficient irrigation methods, and the need for c...
