Hydroponics Monitoring System
With the rise of the internet of things, more and more aspects of life being integrated with technology in novel ways. Furthermore, the rise of digital agriculture is creating ways to improve crop yield and gather meaningful information. In this project, we set out to create a small footprint, vertically scalable gardening system capable of caring for common garden plants.
Our system uses hydroponics, avoiding the need for fertilizer or soil. Instead, the plants are grown in a moisture wicking media that is supplied with nutrient rich solution. A RaspberryPi measures the pH and parts-per-million (PPM) of the nutrient solution. The pH measurements give an indication of how well-suited the solution is to the type of plants being grown, and the PPM measurement indicates the concentration of nutrients in the solution. Both measures are important for ensuring healthy crops. The RaspberryPi is also in control of delivering the nutrient solution and capturing images of the plants to determine their heights. All data is presented to the user through a web UI.
