Carp is a fish species that people do.He turned to feasting the color and shape at present, it has developed a fancy fish species Carp's up. Prices of carp is much higher Breeding carp, it is a disadvantage if the breeding nursery was not enough. Carp will not live with pale affect the price of the sale is that the breeding carp can not be sold at a higher price have. So the rearing carp would be willing to care for. And so much patience. Currently, the detection of ammonia in the pond, there are many ways. Each method requires the cultivation of the self-tests.Causing inconvenience and waste of time is a priority above. Staff had thought to bring a computer program that helps to reduce the burden to the preliminary breeding. Causing more convenient and held a feast that is more efficient, too. For Methodology, we use Arduino for coding program. Main controller board is WeMos D1 WiFi UNO which have wifi for sending information to computer. It connected with 4 Ammonia gas sensors module detector Mq135 and 2 Solenoid water valves 12v that controlled with relay module. Gas sensors will check and collect the average data from 4 sensors all the time when the sensors detects a value that exceeds standard its will send a notification to the user. We set to notify when it exceeds standard and when it dangerous to the fish. When a value that detects was dangerous for the fish the program will commanded relay to open solenoid valve for vary water automatically. The program will save data for predict the time that the user should vary the water.
