AQUAPONICS PH MONITORING SYSTEM USING ARDUINO UNO MICROCONTROLLER
Arief Ismanto · 2021
This application aims to design and implement a circuit that serves to monitor the level of pH levels in water, water pH monitoring is very important to know the good bad water quality. The provision of clean water with poor quality can result in a bad impact on the health of plants and fish, namely the onset of various diseases. Changes in the pH of water can also cause changes in the smell, taste and color of the water. With the development of technology, the existence of sensors and microcontrollers, it is easier to make automatic monitoring tools by using arduino uno microcontroller. Measurement of water pH can be done using pH meter, this method can only be done manually, then made a MICROCONTROLLER ARDUINO UNO R3-based water pH monitoring system to facilitate water pH control so that the process of treatment of plants and ponds becomes better. This temperature sensor works because of the temperature change around the sensor, the detection of non-electrical signals is converted into an electrical signal, usually in the form of electrical voltage, and the change will be displayed on the LCD screen. While the pH sensor measures the pH such as the activity of hydrogen ions surrounding a thin-walled glass bulb at the end. This probe produces a low voltage that is measured and displayed on the LCD screen
