o3 sensor i2c

The USBI2C module can also convert the analogue values on pins I/O2 and I/O3. Before doing this the I/O pins should be set high, effectively making them inputs. Remember though that this is primarily a USB to I2C interface and as such has 4k7 pullup resistors.

The DFRobot Gravity I2C Ozone Sensor (010ppm) is based on electrochemical principles and it can measure the ambient O3 concentration accurately and conveniently. With high antiinterference ability, high stability, and high sensitivity, this Arduinocompatible ozone sensor can be widely applied to fields like portable devices, air quality monitoring devices, disinfection cabinets, and smart ...

13/6/2021· The semiconductor sensor measures the change in electrical conductivity due to adsorption of ozone (O3) gas on the surface of a metal oxide semiconductor (SnO2). When oxygen in the atmosphere is adsorbed on the surface of SnO2 grains, an electron depletion layer is formed on the surface, thereby forming a potential barrier between the grains.
