CO Gas Sensor Module
The CO (Carbon Monoxide) Gas Sensor Module 27931 is designed to allow a microcontroller to determine when a preset CO gas level has been reached or exceeded. Interfacing with the sensor module is done through a 4-pin SIP header and requires two I/O pins from the host microcontroller. The sensor module is mainly intended to provide a means of comparing carbon monoxide sources and being able to set an alarm limit when the source becomes excessive.

Note: Parallax does not provide gas calibration data on the module and such data and alarm setting is the responsibility of the user to define. For information on user calibration please see the documentation.
Precautions:
Be aware that a carbon monoxide concentration greater than 1000 parts ppm (parts per million) is deadly. Automotive exhaust and charcoal cooking grill exhausts can be above 1000 ppm in carbon monoxide.
