OZONE (O ) GAS SENSOR MODULE - PPM User Guide for SRAQ-G015-B Product Description The SRAQ-G015-B gas sensor module detects the presence and concentration of Ozone (O ) gas. Integrated circuitry produces a non-linear voltage signal corresponding to the gas concentration. The SRAQ-G015-B has high sensitivity and selectivity to ozone, and can detect gas concentration in the range of 10 ...

Notes Confirm the polarity and the voltage of the power supply before powering ON the sensor. The analog output of this module is non-linear. When connect to microcontroller, it should be connected to ADC interface of the microcontroller. The relationship between the resistance ratio and the concentration is a logarithmic relationship.
