CARBON MONOXIDE (CO) SENSOR MODULE
User Guide for SRAQ-G012
Product Description
The SRAQ-G012 gas sensor module detects the presence and concentration of carbon monoxide gas. Integrated circuitry produces a voltage signal
corresponding to the gas concentration. Having high sensitivity to this dangerous odorless and colorless gas, the sensor module can detect carbon
dioxide concentrations ranging from 10 to 10,000 ppm. The SRAQ-G012 has both analog and level outputs with adjustable output sensitivity.

  • Page 3 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.
