IOT-BASED MOBILE APPLICATION FOR MONITORING OF HYDROPONIC VERTICAL FARMING

Hydroponic vertical farming is widely seen as a very productive form of farming, at least to some extent. It is a technique of growing plants without soil, which also contributes to the change in how we use space and our resources more efficiently. However, these types of farm setups need a certain environment for the plants to grow and complete their production cycle. One way to achieve this is by continuously monitoring different environmental and nutrient parameters, which is very difficult to do manually. To address this issue, here is a project for an IoT-based mobile app system that monitors and controls hydroponic vertical farming through automation. The brain of the system is an Arduino Mega 2560 which is the primary controller. It collects live data from a range of sensors including a pH sensor for checking the nutrient solution, a DHT11 sensor for recording temperature and humidity, and a soil moisture sensor for determining moisture levels. Besides these, a color sensor and an IR sensor are used to analyze the health and behavior of the plants. The collected data can be displayed locally on an LCD and it is also transmitted remotely via a NodeMCU module.
