| Abstract: | Developed a CO monitoring and alarm systems with the function of SMS.The system uses a combination of singlechip of stc89c52 and MQ-2 sensor monitoring the multi-channel CO.CO concentration is displayed in real time.When the concentration values exceed the threshold,local sound and light will alarm,and GSM module send alarm SMS to the specified phone.CO alarm threshold and phone numbers can be set through the keys.The system has a simple operation,high accuracy,sensitivity,and good control of costs in favor of promotion,meet the design requirements. |
