SEN0465

SEN0465 is a Gravity: Factory Calibrated Electrochemical Oxygen / O2 sensor board. It detects oxygen /O2 concentration and supports 3 O/P modes: analogue, I2C, and UART. The probe has been calibrated at factory, which can quickly and accurately measure the concentration of oxygen / O2 in environment. 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. The probe adopts electrochemical principle, has characteristics of strong anti-interference ability, high stability, high sensitivity, etc, service life is as long as 2yrs. The sensor has 32 modifiable I2C addresses, an integrated temperature compensation algorithm, and threshold alarm function. It has good compatibility with mainstream main control devices such as Arduino, ESP32, and Raspberry Pi. The easy-to-use Gravity interface, coupled with sample code, can quickly build an oxygen / O2 concentration detector.
