Water Flow Control System Based on Context Aware Algorithm and IoT for Hydroponic Farming with using a hydroponic technique became a solution for future farming technique. Hydroponic uses water to provide nutrient and oxygen for the plant. Water must be distributed equally in all part of hydroponic pipes, so that every plants get same amount of nutrient. In order to control the water flow to be distributed equally, this research used servo valve controlled by microcontroller based on Internet of Things (IoT). Lastly, this research also observe the plant grows in the hydroponic that using this system. The result shows that the system can make the plant growth, like plant length and leave width will be more equal between growing tube.

IOT Based Smart Water And Environment Management System Of Paddy Rice At Different Growth Stages Farmers have always invested more than enough time for farming, which, in many cases, has not proven to be fruitful. Paddy rice farmers invest a lot of labor, time and capital only to get a little amount of profit. In many countries like Bangladesh, farmers have complained that they are not able to get the right amount of profit compared to the effort they are putting to grow paddy rice. Our proposed system takes this issue into concern. It encouraged us to create a system which will not only assist the farmers to grow rice but will also consider the little environmental factors and react to them automatically, keeping the farmers away from the rice fields. The farmers can therefore invest this valuable time somewhere else. The system does this by watering the rice plant according to their needs at different growth stages using a water pump. It also controls the temperature and maintains it within a narrow range using electric bulbs and fans. Moreover, this is an IoT based system which actively checks pH of the soil, sends the data to cloud and if the pH is out of range, then it will notify the farmer using the IFTTT application. Furthermore, since this data is being published to the cloud, this could be of real help for geologists as they constantly seek soil quality data of different areas.
