摘要
开发了一款具有短信发送功能的CO监测与报警系统。系统利用STC89C52单片机与MQ-2传感器相结合的方式对多路CO信号进行监测,浓度可实时显示,当浓度超过阈值时本地声光报警,利用GSM模块TC35i向指定的手机发送报警短信。报警阈值、手机号码可通过按键进行设定。系统操作简便、精度高、灵敏度强,并且很好的控制了成本有利于推广,达到了设计要求。
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.
