Description

  • Gravity O2 Sensor (Calibrated) - I2C & UART
  • Detects oxygen concentration
  • Offers high stability and high sensitivity
  • Strong anti-interference ability
  • Adopts the electrochemical principle
  • Supports three output modes: analog, I2C, and UART

The Gravity O2 Sensor (Calibrated) - I2C & UART 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. 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 the electrochemical principle, has the characteristics of strong anti-interference ability, high stability, high sensitivity, etc., and the service life is as long as two years.
