Abstract—GreenhousesProvide Electronics and Communication Engineering a controlled environment for plant cultivation, but traditionalgreenhouse management often depends on manual monitoring of environmental conditions such as temperature, humidity, soil moisture, and light intensity. This manual approach is time-consuming and may lead to inaccurate regulation of plant growth conditions. To address these challenges, this paper presents an IoT-based greenhouse monitoring and controlling systems that enables automatic observationand management of environmental parameters inside the greenhouse. The proposed system integrates multiple sensors including the DHT11 sensor for temperature and humidity measurement, a soil moisture sensor for detecting water content in soil, and an LDR sensor for measuring light intensity. These sensors are connected to an Arduino microcontroller, which acts as the central processing unit and continuously collects environmental data from the greenhouse. The sensed data is transmitted to the cloud through the NodeMCU ESP8266 Wi-Fi module, enabling real-time monitoring using a smartphone or desktop device. The system also includes an automated control mechanism in which actuators such as fans, water pumps, and artificial lighting systems are activated whenever the environmental parameters exceed predefined threshold levels. This automated process helps maintain optimal conditions for plant growth without continuous human intervention. The implementation of this system reduces manual effort, improves monitoring accuracy, and ensures efficient environments. By integrating IoT
