Zhengzhou Winsen Electronics Technology Co.,Ltd Operating Working humidity Storage temp. Working life UART (RXD) 0～3.0V data input UART (TXD) 0~3.0V data output UART output Communication Protocol: 1. General Settings Table 3 Baud Rate Data Bits Stop Bits check bits 9600 8 bytes 1 byte Null 2 .Commands The communication is divided into active uploading and question-and-answering. The factory defaults to active uploading, and the concentration value is sent every 1S. If the user switches to the question-and-answer mode and needs to switch to active uploading again, just send the following command...

Zhengzhou Winsen Electronics Technology Co.,Ltd Active upload data display format is as follows： Table 5 (High Byte) Ambient temperatur Gas concentration value (PPB)=(high gas concentration*256+low gas concentration). When converting to PPM: PPM = PPB/1000 (PPB is known). 1.25×1(PPM) ≈ 1.25mg/m3. Temperature (°C)=((high ambient temperature*256+low ambient temperature)-500)/10. When the user needs the question and answer mode, you can send the following command format to close the active upload data, and then send the command to read the concentration can be. Close the active command line format...
