将模块上的D0输出引脚连接到Arduino上的数字引脚8,将模块上的A0输出引脚连接到Arduino上的模拟引脚 A0。 Arduino代码 代码非常简单,基本上只读取A0引脚上的模拟电压。当检测到烟雾时,它还会在串行监视器上打印一条消息。 #defineMQ2pin (0)floatsensorValue;//variable to store sensor valuevoidsetup() { ...
草图从定义MQ2气体传感器的模拟引脚连接到的Arduino引脚开始。还定义了一个名为sensorValue的变量来存储传感器值。 #define MQ2pin (0)floatsensorValue;//variable to store sensor value 在设置功能中:我们初始化与PC的串行通信,并等待20秒以允许传感器预热。 Serial.begin(9600);// sets the serial port to 9600...
The Grove - Gas Sensor(MQ2) module for Arduino is useful for gas leakage detecting(in home and industry). It can detect LPG, i-butane, methane, alcohol, Hydrogen, smoke and so on.
SeeeduinoGrove-Gas_Sensor-MQ2 5V Red GND Black Not Conencted White A0 Yellow Software there are some examples Please copy and paste code below to a new Arduino sketch, and upload them respectively, If you do not know how to upload the code, please check how to upload code....
