How pH affects Nutrient Absorption in Plants

Sensors for Hydroponics Hygrometer pH Sensor Temperature and Humidity Sensor Water Level Float Switch 13 13 13

Control Unit Will be a Raspberry Pi model b+ Connected to app through Wi-Fi Uses inputs from sensors (pH, water level, etc.) Controls the hydroponic pumps and the lighting 14 14 14

App Shows sensor data in graphical form Tells the user when more water or nutrients need to be added Requests simple user inputs about changes in plants Will offer tips on how to handle and harvest plants 15 15 15

Concerns and Fallbacks UV Light can damage eyes UV blocking film Complexity of nutrient dispersal system Lead times on sensors Testing time Assembly time Start early 16 16 16

MDR Deliverables Hydroponic mock-up Functional nutrient dispersal system At least 1 sensor reading to control unit Lighting interfaced with control unit Android Application skeleton 17 17 17
