Development of an Affordable Bluetooth-based Measuring System to Analyze Water Quality for Hydroponic Plants

Hydroponic farming is a modern method of farming that involves growing crops and plants in an artificially maintained water-medium, without the use of soil. It is said to be the future of agriculture since it has been showing great promise over the past few years. This system consists of the essential sensors such as pH sensor and a waterproof temperature sensor to measure water quality, an Arduino Microcontroller and a Bluetooth module that is used to connect the entire system to a phone. The data from the sensors is processed by the Arduino Microcontroller and the code running the system sends this sensor data to an android phone via a low-cost, low-energy Bluetooth module. This data can then be seen and recorded on the android phone in an open source application that was created particularly for this project, keeping in mind the need of simplicity.
