Gravity: O2 Sensor (Calibrated, I2C & UART) _ARD_SHIELD_NANO Included is a built-in 500mAhThis is a sensor that detects oxygen concentration and supports three output modes: analog, I2C and UART. The probe has been calibrated at the factory, which can quickly and accurately measure the concentration of oxygen in the environment. This type of sensor can be widely applied to fields like portable devices, air quality monitoring devices, industries, mines, warehouses, and other spaces where the air is not easy to circulate and requires
