In order to solve the problems that methane gas detection have bad instantaneity and low piecision in current family life and industrial production

a kind of infrared methane detection system based on the Wi Fi technology is designed. Detection part adopts the metnane sensor based on non-dispersive infrared method

wireless communication part adopts Wi Fi serial interface module

and combine with the mobile phone App to realize remote real-time detection of methane gas concentration. The detecting principle of infrared methane sensor and the design of hardware and software of detection system are introduced mainly. The calibration experiment of methane sensor is carried out

and using the algorithm of SVM for regression correction. The detection system improves the instantaneity and piecision of the methane detection and effectively prevents the explosion accidents caused by personal negligence. So

it has certain application value.
