When the sensor is stored, the working electrode and the reference electrode should be in an open state.In a high-concentration gas environment, it is slow to return to the initial state after long-term use.Do not use the case if it is damaged or deformed.The sensor must not be subject to excessive impact or vibration.The waterproof and breathable membrane above the sensor is strictly forbidden to be opened or damaged.The intake surface of the sensor must not be blocked or polluted.When testing and applying the sensor, the front vertical intake must be avoided.All electrochemical sensors should not be used in environments containing corrosive gases, which can damage the sensor.All electrochemical sensors cannot be completely encapsulated with resin materials, nor can they be immersed in an oxygen-free environment, otherwise the performance of the sensor will be damaged.The sensor avoids contact with organic solvents (including silica gel and other adhesives), paints, chemicals, fuel oils and high-concentration gases.Electrolyte leakage will cause damage, please do not disassemble the sensor at will.Compatible with both 3.3V and 5V micro-controllers.V1.1 I2C address can be switched 0X70, 0X71, 0X72, 0X73(upgrade to V1.1 on 3) Features V1.0 I2C address can be switched 0X72, 0X73 With simple Gravity interface and practical sample code, you can build your own oxygen concentration monitor easily and conveniently.
Moreover, the lifetime is as long as 2 years. It supports wide range input voltage: 3.3V to 5.5V. Its effective range is 0~25%Vol, and resolution can reach to 0.15%Vol. It is compatible with many mainboards like Arduino Uno, esp32, Raspberry Pi and so on. This compact dfrobot oxygen sensor supports I2C output, it can be calibrated in the air, can accurately measure the oxygen concentration in the environmentit.
