User Guide for SRAQ-G019
Product Description
The SRAQ-G019 gas sensor module detects the presence and concentration of Ammonia, as well as other organic amines such as trimethylamine
and ethanol. Integrated circuitry produces a non-linear voltage signal corresponding to the gas concentration. With a detection range of 5 to 500 ppm,
the SRAQ-G019 industrial sensor can be used in areas such as public restrooms, manufacturing facilities, warehouses and other commercial
buildings where ammonia gas concentration is a concern.

  • 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.
