Product description: O2 oxygen sensor with I2C communication
Sensor designed for measuring O2 concentration in the environment. The DFRobot product is compatible with3.3 Vand5 Vcontrollers such asArduino, ESP32 orRaspberry Pi. It communicates via theI2Cinterface and is very resistant to interference. The sensor range isfrom 0% to 25% volume. It has a quick calibration function and high measurement sensitivity.
The use of special protection against polarity additionally extends its lifetime. It is widely used as a device for monitoring air quality in places with difficult circulation, such as mines or warehouses. Simple Gravity interface and sampleprogramcode provided by the manufacturer guarantee comfort and ease of use.
Product compatible with Arduino The manufacturer has prepared auser guide andlibrary with asample program forArduino users. |
Botland is an official distributor of DFRobot open-source hardware. Every roboticist and practitioner of emerging technology has heard at least once of DFRobot solutions, built above all around Arduino. Our range holds original DFRobot products only.
Module outputs
The sensor module works with main components communicating via the I2C interface. To read the data, supply power and connect the output pins to the relevant microcontroller inputs.
