Nitrate & PH checker for water quality of aquaponic system / Mohamad Alif Isaac Ismet Benyamin

Aquarist, which also means a fishkeepers will use a lot of method in order to make the environment inside the aquarium is clean and safe for the aquatic animals. One of the methodasare checking the nitrate in the water. The reason behind of checking the nitrates are that build-up of organic compounds and fish waste in your aquarium is indicated by high nitrate levels, which can lead to poor water quality and an increase in the growth of algae. On the other hand, fish and invertebrates are healthier when the nitrate level is kept low. Thus, using test kit for nitrates, there are a lot of instructions that needs to be followed to make sure the value we get is accurate. Therefore, this is where Nitrate Checker system and pH Checker comes in handy. Nitrate Checker system which uses Arduino Mega 2560, it will be consist of a timer(countdown)system that uses a motor and a buzzer. To make things easier, each countdown for the timer will be displayed on a 20x4 LCD display This Nitrate Checker system will help the aquarist in terms of getting ready the nitrate test solution by only using the machine. On the other hand, the pH Checker system that uses an ESP32S NodeMCU will be a portable system that checks the pH value of an aquarium water which can be checked on an app inside your smartphone (Blynk) and also store your data of your past pH value measurements.
