Gravity: Analog Dissolved Oxygen Sensor / Meter Kit for Arduino Category_Grove (Arduino)/Grove Radio/RF Along with the Speaker AmpThis is a dissolved oxygen sensor kit. A dissolved oxygen meter is used to measure the dissolved oxygen in water, to reflect the water quality. It is widely applied in many water quality applications, such as aquaculture, environment monitoring, natural science, etc. Theres an old saying regarding keeping fish, Good fish deserves good water. Good water quality is very important to aquatic organisms. Dissolved oxygen is one of the important parameters
