Design of pH Testing System Based on ARM

Abstract:

Article Preview

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.
