As the number of fish keepers increases, fishbowl-related convenience products are on the rise. Existing products are not welcomed by consumers because of their lack of functions or high price. In this paper, we deal with a system that remotely controls sensors and motors of fish bowl based on Raspberry Pi and Arduino. In Android applications, you can use the following functions. firstly, feeding. Second, water changing. Third, it measures, visualizes temperature and pH values including alert function. Through the several experiments, it was verified that the system can be quickly accessed from the outside, and when it is appropriate to change water. This system allows the user to keep the fish more comfortable and safe.
