Rancang Bangun Sistem Monitoring Ph Air Kolam Pembibitan Ikan Patin Menggunak…

Design of monitoring ph pool water of catfish breeding using GSM 900A module on arduino. The purpose of this research is to design a monitoring system to support catfish breeders in knowing the acidic and alcali pH levels water. Arduino Nano is a programmable tool for processing water pH sensor reading data. The workings of this tool is, when the pH sensor which is an input is put in water, the…
