This based on multi-MCU AT89S52 gas detection system source code, gas sensor using a VIA' s MQ series (I use the MQ-2), can detect ethanol, methane, gas, sulfur dioxide and other gases. Specific hardware, the sensor output data converted by the TLC549 serial data acquisition and processing directly to the microcontroller and then sent LCD1602A show! Very strong ~
