MONITORING AND CONTROLLING OF GREENHOUSE

Abstract

The main idea of this project is to control the temperature, light, and irrigation system inside the greenhouse to provide an appropriate growing environment to plants. The environmental factors inside the greenhouse are studied, and appropriate circuit to control those factors is designed and implemented using suitable components. To control these environmental factors suitable sensors are used such as temperature sensor (LM35) and light sensor (LDR). Sensors input a certain voltage according to the measured factor, after that the microcontroller compares between the measured value and the reference one and switches on the appropriate actuator
