| Summary: | 碩士 === 國立勤益科技大學 === 電子工程系 === 102 === With the popularity of fish farming by now, many people have begun fish farming at home and in the company. However, in the aquarium fish, the most likely murderer to lead biological death is the ammonia. In the course of fish farming, the novice is most easily to overlook the ammonia in the water, resulting in the death of aquatic life, so the system is designed to remind pet owners.
The system used an OV sensor to interpret the color changes of the paper, and was installed with the automatic pumping system. This system helps users detect the ammonia mount in the tank regularly. The color read by an OV sensor was converted into the concentration displayed on the LCD to remind users of avoiding high concentrations of ammonia in the tank, causing biological death.
The system was divided into two parts: the first part is the algorithm between the color of test papers and ammonia concentration, and the second part is to retrieve the effective response range of test papers.
