DO6400

The DO6400 sensor consists of two electrodes, an anode and cathode, immersed in electrolyte and separated from the water of interest by an oxygen permeable membrane. Oxygen diffuses across the membrane and reacts with the cathode to produce a current proportional to the amount of oxygen that has diffused into the sensor. DO sensors therefore actually measure the partial pressure of the oxygen in water; higher pressure allows more oxygen to diffuse across the membrane and more current to be produced. The current is converted to a millivolt output, which can be directly measured with a WSN wireless node. These sensors are typically used for aquaculture and wastewater monitoring applications and require minimal maintenance.
