摘要

The pH measuring instrument is mainly applied to measure the pH value of the solution, widely used in industry, agriculture, scientific research and environmental protection. The paper proposes a pH measuring system based on ARM. The measuring dataes of the pH composite coloured glaze electrode and the temperature sensor are put into ARM ADC channels, displaying the results of the pH and the temperature after analysing. Touch screen can operate corresponding actions, such as beginning, selecting, confirming. This instrument uses safely, can monitor real-time and fixedly, higher precision, which can be used in agricultural.
