Greenhouses are climate controlled structures with walls and roof specially designed for off season growing of plants. Most greenhouse systems use manual systems for monitoring the temperature and humidity which may cause discomfort to the worker as they’re sure to visit the greenhouse daily and manually control them. Also, tons of problems can occur because it affects the productivity rate because the temperature and humidity must be constantly monitored to make sure that yield of the plants increases. Internet of Things is among one of the newest advances in Information and Communication Technologies, providing global connectivity and management of sensors, devices, users with information. So the combination of IOT and embedded technology has helped in bringing solutions to several of the prevailing practical problems over the years. The sensors used here are YL69 moisture sensor and DHT11 (Temperature & Humidity sensor). From the info received, Microcontroller automatically controls Moisture, Temperature, Humidity efficiently inside the greenhouse by actuating an irrigating pipe, cooling fan, and sliding windows respectively consistent with the specified conditions of the crops to achieve good growth and yield. The recorded temperature and humidity are stored in a cloud database (Thing Speak), and the results are displayed in a web-page, from where the user can view them directly.
