Abstract The high precise pH automatic monitoring measurement is designed based on MSP430 MCU and pH sensor. To eliminate the effect of temperature on the measurement results, a pH value temperature compensation module is established using the least Squares Method to analyze the linear relationship between pH and voltage. The results show that, the automatic monitoring measurement possesses broad application prospects with the advantages of ultra-low power consumption, good stability and high precision.
