IoT pH regulator with Arduino and Blynk

In this project I will show you how to build a basic pH regulator using cheap electronic components that are readily available online. The regulator can be controlled and monitored online through the Blynk app dashboard and through interaction with the device.

This project is easily modifiable to use other types of components, like peristaltic pumps or liquid valves to regulate pH up or down, depending on what kind of project/system that you are using it with. It can be modified to supply both pH hightening and pH lowering agents, which can be used in gardening systems like hydroponics/aquaponics where pH can both rise and fall depending on the many enviromental factors in the system.
