The design is based on SCM gas concentration measuring instrument, the system microcontroller AT89S52 as the core sampler containing gas concentration, AD conversion circuits, LED display and alarm devices and other components. The sensor can be effective monitoring of underground low concentration and high concentration of gas, try a very wide range. Transmitting monitored information to the microcontroller, issued a directive after the microcontroller processing, if the gas exceeds the predetermined value, the system can automatically send an alarm and immediately s instructions to reduce the gas concentration.
