Revolutionizing Farming: Experimental Design and Development of NodeMCU Assisted IoT based Smart Irrigation System

This research introduces an innovative IoT-based Smart Irrigation System named WiFi Smart Irrigation (WiFiSI) that leverages advanced sensors and communication technologies to optimize irrigation practices. The system incorporates a diverse set of sensors, including the SEM225 RS485 Soil Moisture Sensor, DS18B20 Digital Temperature Sensor, AM2302 Humidity Sensor, JXCT Soil NPK Sensor, 6025 Chlorophyll Sensor, LDR (Light Dependent Resistor), and a GSM module. The SEM225 RS485 Soil Moisture Sensor provides accurate soil moisture data, while the DS18B20 Digital Temperature Sensor and AM2302 Humidity Sensor monitor ambient conditions. The JXCT Soil NPK Sensor assesses soil nutrient levels, and the 6025 Chlorophyll Sensor evaluates plant health. Additionally, the LDR helps gauge light intensity, aiding in determining optimal irrigation periods. The WiFiSI system integrates these sensors to collect real-time data, which is then processed and analyzed to make informed irrigation decisions. Through a WiFi connection, the system enables remote monitoring and control, allowing users to access data and adjust irrigation settings from anywhere. The inclusion of a GSM module ensures connectivity even in areas with limited WiFi coverage, enhancing system reliability. The proposed Smart Irrigation System aims to improve water efficiency, minimize resource wastage, and enhance crop yield by providing farmers with actionable insights into soil and environmental conditions. The multi-sensor integration, coupled with IoT capabilities, empowers precision agriculture, making irrigation practices more sustainable and environmentally friendly.
