Zhengzhou Winsen Electronics Technology Co.,Ltd UART (RXD) 0~3.0V Data input UART (TXD) 0~3.0V Data output Communication Protocol 1 General Settings Table 3 Baud Rate Data Byte Stop Byte check bits 2 Communication Commands There are two communication type: active upload type and Question & Answer type. The default type for this module is active upload and it sends gas concentration every other second. If it is Q&A mode and you want to switch it to active upload mode again, please send following command: Command to switch Q&A mode to active upload mode: Start Byte Full scale Full scale Data of...

Zhengzhou Winsen Electronics Technology Co.,Ltd Command to turn off active upload mode: Start Byte Switch command Read concentration under Q&A mode: Start Byte Return gas concentration as follow: Byte0 High Byte(ppb) NOTE: Gas concentration(PPB)=(Concentration high byte*256+Concentration low byte). If users would like to change the unit into PPM: PPM=PPB/1000. 3 Checksum calculation method Checksum = (Negative (Byte1+Byte2+Byte3+Byte4+Byte5+Byte6+Byte7)) +1 unsigned char FucCheckSum(unsigned char *i,unsigned char ln) { unsigned char j,tempq=0; i+=1; for(j=0;j<(ln-2);j++) { tempq+=*i; i++; } tempq=(~tempq)+1;...

Zhengzhou Winsen Electronics Technology Co.,Ltd 6. The module cannot be completely encapsulated with resin material, nor can it be immersed in an oxygen-free environment, otherwise the performance of the sensor will be damaged. 7. The module can not be used in the environment containing corrosive gas for long time because corrosive gas will damage the sensor. 8. The module should not withstand excessive shock or vibration. 9. The module needs to be warmed up for 24-48 hours at the first power-on, so that the module is fully stabilized and tested normally. 10.The white waterproof and breathable...
