Analog pH adapters typically map 0V-5V to 0-14 pH. For Arduinos (10-bit ADC, 0-5V): for measured value adc:
pH = (adc_value / 1023.0) * 14.0
Always cross-check calibration curves in your kit's datasheet-different brands (such as DFRobot or generic) may have slight offset/scaling variations.
For long-term projects, order extra buffer sachets and replacement probes directly from the Sensors or All Products categories.
