Features

Simple and intuitive API for interacting with the PH4502 sensor.
Supports pH measurement with high precision and accuracy. Automatic temperature compensation for more accurate readings.
Flexible calibration options to ensure optimal performance.
Lightweight and efficient implementation for resource-constrained Arduino boards.

Installation

To use the PH4502 Sensor Arduino Library, follow these steps:

Installation on Arduino IDE

Just type "PH4502C-Sensor" on the Library Manager of the Arduino IDE.

Alternatively you can follow the steps below:

Download the library by clicking on the "Download" button or clone it using Git:

git clone https://github.com/nthnn/PH4502C-Sensor.git
Place the downloaded library folder into the Arduino libraries directory on your computer. In Windows, the default location is usually:

[Arduino Documents Folder]/libraries/
Launch the Arduino IDE. Then, click on "Sketch" and then navigate to Include Library. You should see the newly added "PH4502-Sensor" option. Click on it to include the library in your sketch.

Now you are ready to use the PH4502 Sensor Library in your Arduino projects.

Installation on PlatformIO

Type "PH4502C-Sensor" on the PlatformIO library registry, and click "Add Project." And that's it!

Getting Started

To begin using the PH4502 Sensor Library, follow these simple steps:

Connect your PH4502C sensor to your Arduino board. Make sure to connect the appropriate VCC, GND, and data pins based on your Arduino model and pin configuration.
In your Arduino sketch, include the PH4502C Sensor Library by adding the following line at the top of your code:

#include <ph4502c_sensor.h>

ph4502c_sensor.h
Arduino Library for PH4502C Sensor.

Create an instance of the PH4502C_Sensor class:

PH4502Sensor ph4502c(A0, A1);

// Analog Pin 0 - pH level pin

// Analog Pin 1 - temperature pin

Initialize the sensor in the setup() function of your sketch:

cpp void setup() { // Initialize the sensor ph4502c.init(); }

Read the pH value from the sensor using the readpH() function:

```cpp void loop() { // Read pH value float pHValue = ph4502c.read_ph_level();

// Do something with the pH value // Delay before next reading delay(1000); } ```

Optionally, you can calibrate the sensor for better accuracy. Refer to the library [documentation](docs) for more information on calibration.
