IOT Based Greenhouse Monitoring and Control System

Abstract—The integration of IoT in agriculture has revolutionized farming by making it smarter, more efficient, and less labor-intensive. This project presents an IoT-based greenhouse monitoring and automation system designed to optimize plant growth, reduce manual effort, and conserve resources like water and electricity.At its core is a NodeMCU (ESP8266) microcontroller connected to a DHT11 sensor (temperature and humidity), a soil moisture sensor, and an LDR (light sensor). These sensors continuously monitor greenhouse conditions and send real-time data to a web-based dashboard accessible from any internet-enabled device.Users can view live environmental data and remotely control actuators such as a fan, water pump, and light bulb—helping maintain ideal conditions for plant growth efficiently and automatically.
