Communication Protocol

General Settings

Communication Commands

• There are two kinds of communication: initiative upload mode and question-and-answer mode. The default setting is initiative upload mode. Modules upload gas concentration values every other 1 second.
  • Note: The module will automatically switch to Q&A mode (question & answer mode) after receiving an inquiry command. The module will automatically switch back to initiative upload mode if no inquiry command is received within 30 seconds under Q&A mode.

Initiative Upload Data Format

Gas name: 0x04 is for CO.

Communication Commands

There are two kinds of communication, initiative upload mode and question-and- answer mode. The default setting is initiative upload mode. Modules upload gas concentration values every other 1S,
Note: The module will automatically switch to Q&A mode(question & answer mode) after an inquiry command is received; The module will automatically switch to initiative upload mode if no inquiry command is received within 30 seconds under Q&A mode.

Table 4 Initiative upload data format

• Gas name: 0x04 is for CO.
• Concentration (High Byte): The highest bit(bit 8) is for sensor fault judgment;
• Note: sensor fault judgment: 1 is for sensor failure, 0 is for no failure.
• Gas concentration value = (The low 5 bit of High Byte256+Low Byte)0.1.
• Full range= full range (high byte)*256+ full range(low byte) (0X1388=5000ppm, which means the module range is 500ppm)

To read gas concentration, the command line format is as follows: Stable5.

• Concentration(High Byte): The highest bit(bit 8) is for sensor fault judgment;
• Note: sensor fault judgment: 1 is for sensor failure, 0 is for no failure.
• Gas concentration value = (The low 5 bit of High Byte256+Low Byte)0.1.

Check sum and calculation

Check = (negation(byte1+bye2+……+byte7))+1 Please refer the following example:

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; return(tempq);}

Cautions

1. DO NOT insert or extract the sensor on the PCB board.
2. DO NOT change or move the electronic part of the module.
3. Avoid sensor contact with organic solvents, coatings, medicine, oil and high-concentration gases.
4. Excessive impact or vibration should be avoided.
5. Please keep the modules warming up for at least 5 minutes when first using them.
6. Please do not use the modules in systems which related to human being’s safety.
7. Please do not use the modules in a strong air convection environment.
8. Please do not expose the modules to high-concentration organic gas for a long time.
