Agrisense: An IOT-Driven Smart Monitoring and Automated Irrigation System for Precision Farming

Traditional agriculture practices often rely on manual monitoring of environmental conditions and irrigation schedules, which can lead to inefficient water usage, crop stress, and reduced yield. While several automated solutions exist, many are either cost-prohibitive or lack real-time remote monitoring capabilities. This paper presents an IoT-Based Smart Agriculture Monitoring and Irrigation System that leverages the ESP32 microcontroller, DHT22, soil moisture sensor, LDR, and cloud integration through ThingSpeak to automate crop management. The system provides real-time monitoring of temperature, humidity, soil moisture, and light intensity, and controls irrigation via a relay module when soil moisture falls below a set threshold. A 20×4 LCD displays local readings while ThingSpeak provides remote access and analytics. In a pilot implementation, the system demonstrated improved irrigation efficiency, timely water application and reliable environmental monitoring, offering a scalable and cost-effective solution for modern precision agriculture.
