GSM Based Irrigation System In this modern world agriculture plays a vital role in the development of the country, economy and its people. Agriculture depends a lot on the source and supply of water and that becomes a major issue in places which rely solely on the monsoons as their primary source of water, since the monsoons are not evenly distributed all over the country every year. In such cases, the scheduled watering of the crops can get hampered, and that might in turn hamper the quality and quantity of crops produced. To overcome this problem, the proposed smart irrigation system can be employed in the field of agriculture. In agriculture, apart from a water source, two more aspects are of prime importance, namely, the moisture content of the soil and its fertility. In this system, based on the soil type and the moisture levels, water will be provided to the agricultural field. At present, there are several techniques available to reduce the dependency on seasonal rain for agriculture. Mostly these techniques use electricity. However, in this paper our aim is to propose a low cost, sustainable solution to the problem of water supply in indoor cultivation, farms and agricultural fields.

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.
