烟雾浓度传感器Z-MQ-01,Z-MQ-01模组采用MQ-2 气体传感器配合8 位高性价比单片机，内部已做AD 采集，用户只需对串口读数据即可，方便使用。该模组对液化气、丙烷、氢气的灵敏度高，对天然气和其它可燃蒸汽的检测也很理想。单片机设置好与模块相同的波特率后，根据通信协议，通过TXD、RXD脚与单片机进行串口通信，在收到单片机发出的开始信号后，将模块采集的烟雾浓度数据发送给单片机，对返回的数据进行处理即可得到所需烟雾浓度参数。(Smoke concentration sensor z-mq-01,Z-mq-01 module adopts mq-2 gas sensor and 8-bit high cost performance single chip microcomputer. Ad collection has been done inside. Users only need to read data through serial port, which is convenient for use. The module has high sensitivity to liquefied gas, propane and hydrogen, and is also ideal for the detection of natural gas and other flammable vapor. After setting the same baud rate as the module, the single-chip microcomputer communicates with the single-chip microcomputer through TXD and RXD pins according to the communication protocol. After receiving the start signal from the single-chip microcomputer, the smoke concentration data collected by the module is sent to the single-chip microcomputer, and the returned data is processed to obtain the required smoke concentration parameters.)
