In today’s world, it is noticeable that everyone in all different fields of life is seeking for something that can make life easier. In terms of household chores, there are several smart inventions to make people easier especially housewife. From our research, the title of our project is Freshness of Fish Detector. This project is specially design to detect either the fish is still fresh or not In our daily life, we always have the problem to buy the fresh fish at the market. So we have decided to do this project to settle down the problem. In this project, the concept of the detector is same like pH sensor. The pH detector measures how acidic or basic a substance is. The pH detectorr ranges from 0 to 14. A pH of 7 is neutral, a pH less than 7 is acidic and a pH greater than 7 is basic. If the fish is fresh the scale will below than pH 7 and the range of the 0-6 will display on liquid crystal display (LCD). If the fish is not fresh the scale will above than pH 7 and the range of die 8-14 will display on LCD and also the buzzer will buzz. Therefore, in order to solve the problem we have come up with a solution. A battery 9V used in this project.
