Please read this information prior to installation.

IMPORTANT INFORMATION: This sensor is model number: SEN0322. If you are using an Arduino, make sure that use use the library called, DFRobot_OxygenSensor. Do not use the library called DFRobot_EOxygenSensor, as this is for the sensor model SEN0496 and WILL NOT work with this sensor. As for the sensor itself, it it easy to setup (with the correct library) and appears to work flawlessly.
