The increasing demand for sustainable agricultural practices has led to the integration of IoT technology into farming. This paper presents the Smart Agro-Climate Advisory System, an IoT-based smart farming solution that monitors soil moisture, temperature, humidity, and motion detection while automating irrigation. The system is designed to enhance agricultural efficiency by reducing water wastage and providing real-time environmental insights to farmers. Utilizing NodeMCU ESP8266, Soil Moisture Sensor, PIR Motion Sensor, and a Relay Module, the system ensures efficient water management and security for crops. The Blynk IoT platform enables real-time data visualization, remote irrigation control, and security alerts through a mobile application. The automation of irrigation using real-time soil moisture data significantly minimizes water overuse while optimizing crop health. Additionally, the inclusion of a PIR motion sensor enhances security by detecting unauthorized movement within the field, alerting the farmer through the IoT platform. This research explores the system's architecture, implementation, and advantages, demonstrating how IoT-based solutions can revolutionize traditional farming methods. By leveraging cloud-based analytics and automation, the Smart Agro-Climate Advisory System provides an effective approach toward precision agriculture, water conservation, and smart farming, ultimately ensuring sustainable agricultural growth.
