Temperature has an impact on pH value of water and composite electrode potential of pH sensor
through analysis on pH measurement principle
put forward temperature compensation model based on least squares method
design pH value measurement system using ATMEGA128 MCU as core controller. The analysis on test data show that the measurement precision is higher in this system
