Sensors play a crucial role in modern biomedical applications. This research study attempts to implement a novel model to calculate the heart rate, blood oxygen level, blood pH value and temperature ...

pH Sensor with Arduino and Display System The pH Sensor with Arduino and Display System is a compact and efficient solution for measuring and displaying the pH levels of soil or water. By connecting ...

Arduino Code Here's a simple Arduino code to read the pH value from the sensor and print it to the Serial Monitor. If using an LCD, you can add the necessary code to display the value on the LCD.

We connected $\\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The sensor was ...
