| Summary: | The objective of this study is to design and construct a prototype for pH Based Food Analyzer which is easy to use by anyone without extensive training. This sensor is used in determining the pH level in food. The chemical reaction that occurred can produce contaminant or spoilage in food and can affect the pH level. With this pH Based Food Analyzer, the pH level of food can be monitored. This project includes the study on chemical reaction and also on sensor circuit. It is divided into three parts ; recognition element, transducer and signal processor. Throughout this project, electrochemical transducer with ionic recognition is used. The sensor used is connected to amplifier in order to amplify the voltage produced. The amplifier then connected to computer through data acquisition (DAQ) card. The result of pH level is displayed using software LabView. |
