Using an Arduino NANO or just about any Arduino you can create a very accurate PH & EC/TDS meter for hydroponic and gardening. Connect your Arduino to your computer, start the Arduino IDE and flash ...

Arduino-pH-meter A simple project to measure the pH of a solution using an Arduino-based pH sensor and a web page that plots pH over time.

Background: Accurate pH measurement is vital in diverse settings such as water quality assessment, food production, and laboratory procedures. This study introduces a pH meter design utilizing the ...

In this article, we present a pH meter that can accurately measure the pH value of a solution. We use a dedicated sensor, the Arduino UNO R4 Minima board.

The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass. The device is termed as pHduino which can operate by ...

Measuring pH Value With Arduino UNO R4 If you want to know the acidity (or basicity) level of your pool or aquarium water, you need a pH meter. In this article, you'll find a simple but effective ...

Here we build the portable TDS meter that checks the TDS level of water in real-time, enabling us to maintain the right pH level of water.
