Abstract

Increase in temperature may also lead to an increase in the number of ions in solution due to the dissociation of molecules. As pH is a measure of the hydrogen ion concentration, a change in the temperature of a solution will be reflected by a subsequent changein pH. In addition, changes in temperature will also have an influence on the measure in sensor used. The temperature sensor and pH probe are used in conjunction with the microcontroller circuit to measure various pH levels and temperature ranges. The Liqid Cristal Display (LCD) module is interfaced to display the measured results. Several different testing methods are available for measuring temperature values. For measurement of the temperature values, it is crucial to choose the right DS18B20 Digital Temperature Sensor. A pH meter measures the potential difference (in mV) between the electrodes and converts it to a display of pH.
