Abstract: This system is designed with the aim to facilitate the farmer or gardener to engage in greenhouse plantations and improve agricultural production. The main focus is to design an automated ‘Green House’ system which is a smart technology to supply garden plantations grown in a certain green house or similar garden area with the required amount of water, temperature and sunlight and avoid damage of the plantations due to over or under supply of this particular plant nourishments. The system monitors and controls the soil moisture, temperature and light intensity based on the three sensors and the Arduino module that automatically controls a water pump, a fan and a lighting fixture based on the sensor information in the greenhouse.
