Climate change and the growing population are the two of the most important causes for the reduction of the arable lands around the world. This makes the cultivation of crops for farmers more difficult. So, to overcome this difficulty we can implement hydroponics which are plants that do not necessarily require soil for their growth. As the majority of the earth's surface is covered by water bodies, hydroponics will be a huge benefit. Hydroponics means a soilless cultivation technique in which the plants are irrigated with a nutrient solution consisting of water and compounds necessary to provide all the essential elements for normal mineral nutrition. For the plants to retain all the nutrients there must be a well-balanced system to monitor them. So, we present a prototype of a hydroponic greenhouse integrated with IOT technology and a Dashboard for viewing data in real time which allows remote monitoring and control of components. We build a system that is capable of monitoring the atmospheric conditions as well as the plant conditions at any time. The dashboard created allows the user to monitor the conditions even from remote places. In this project, we suggest creating a smart hydroponic greenhouse that uses sensors to track the greenhouse's temperature, humidity, light, and water level. Wi-Fi is used to transmit all of the sensor's data to a cloud server, where it is presented in real time on a dashboard with the option for the end user to remotely turn on and off certain components.
