摘要：As both carbon monoxide (CO) and carbon dioxide (CO2) exit during a fire, they are obvious indicators for the need to be alert to the possibility of fire. Another problem concerning poisoning by carbon monoxide (CO) is asphyxiation that occurs in houses during winter. The development of an automatic gas poisoning prevention system in conjunction with a ventilation function using carbon monoxide/carbon dioxide sensors would prove beneficial, necessary. As presented here, this system includes two gas sensors, an alarm, a ventilation device, a motor, and a rain-protection louver. The louver is manipulated by a motor. Two thresholds of gas concentration are preset inside the microcontroller via a PC. The louver is opened by the motor as the first threshold of gas is reached. Additionally, an alarm system is triggered and the ventilation fan starts up if the second threshold of gas concentration is reached. Consequently, image-monitoring via the PC is established using an IPCAM.
