CO2 (Carbon Dioxide) Gas Sensor Module
The CO2 (Carbon Dioxide) Gas Sensor Module 27929 is designed to allow a microcontroller to determine when a preset Carbon Dioxide 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 dioxide sources and being able to set an alarm limit when the source becomes excessive.
