SEN0322

SEN0322 is a Gravity I2C oxygen sensor is based on electrochemical principles and it can measure the ambient O2 concentration accurately and conveniently. With high anti-interference ability, high stability and high sensitivity this Arduino-compatible oxygen sensor can be widely applied to fields like portable device, air quality monitoring device and industries, mines, warehouses and other spaces where air is not easy to circulate. This compact oxygen sensor supports I2C output, it can be calibrated in the air, can accurately measure the oxygen concentration in the environment. It is compatible with many mainboards like Arduino Uno, esp32, Raspberry Pi and so on. Its effective range is 0 to 25%Vol and resolution can reach to 0.15%Vol.
