inline

Construct a new PH4502C_Sensor object.

Parameters

ph_level_pin	Analog pin connected to the pH level output of the sensor.
temp_pin	Analog pin connected to the temperature output of the sensor.
calibration	Calibration value to adjust pH readings (default is PH4502C_DEFAULT_CALIBRATION).
reading_interval	Time interval between consecutive pH level readings in milliseconds (default is PH4502C_DEFAULT_READING_INTERVAL).
reading_count	Number of pH level readings to average when using read_ph_level() (default is PH4502C_DEFAULT_READING_COUNT).
adc_resolution	ADC resolution used for voltage calculation from the analog read (default is PH4502C_DEFAULT_ADC_RESOLUTION).

Member Function Documentation

◆ init()

void PH4502C_Sensor::init ( )

Initialize the PH4502C sensor.

This function sets up the necessary configurations for the sensor. It should be called in your setup() function.

Definition at line 4 of file ph4502c_sensor.cpp.

◆ read_ph_level()

float PH4502C_Sensor::read_ph_level ( )

Read and calculate the pH level.

Returns: The calculated pH level. This function reads the analog signal from the pH sensor, converts it into a pH value, and returns the result.

Definition at line 13 of file ph4502c_sensor.cpp.

◆ read_ph_level_single()

float PH4502C_Sensor::read_ph_level_single ( )

Read and calculate the pH level without averaging multiple readings.

Returns: The calculated pH level. This function is used when you require a single pH reading without the benefit of averaging multiple readings.

Definition at line 28 of file ph4502c_sensor.cpp.

◆ read_temp()

int PH4502C_Sensor::read_temp ( )

Read the temperature from the sensor.

Returns: The temperature reading in degrees Celsius. This function reads the analog signal from the temperature sensor and returns the temperature in degrees Celsius.

Definition at line 37 of file ph4502c_sensor.cpp.

◆ recalibrate()

void PH4502C_Sensor::recalibrate ( float calibration )

Recalibrate the sensor with a new calibration value.
