MEMS Module Series Communication Protocol 1 General Settings Table 3. Baud Rate Data Bits Stop Bits 2 Commands Communications are divided into active uploads and Q&A. The default communication mode is active upload mode, module sends the concentration value every 1s interval. If user switches to Q&A mode, and needs to switch from Q&A to active upload mode, send command as below: Table 4. Byte0 Start Byte Switch Command Active Upload Data format under active upload mode is as following: Table 5. Byte0 Low byte of gas concentra tion High byte of full scale Low byte of full scale Start Byte Decimal...

MEMS Module Series Command format of reading concentration, under Q&A mode is as following: Table 7. Byte0 Start Byte 0xFF High byte of full scale Low byte of full scale Return value as below: Table 8. Byte0 High byte of gas concentrati on Decimal point Need to convert hexadecimal data to decimal data For example: FF 86 01 C2 02 00 03 E8 CA Gas concentration =( HIGH byte of full scale* 256 + LOW byte of full scale)*Resolution Gas concentration =(1*256+194)*0.01=4.50 mg/m3 A decimal place of 0 indicates a resolution of 1; a decimal place of 1 indicates a resolution of 0.1; and a decimal place...

MEMS Module Series Instructions Preheating time The sensors resistance will drift reversibly if it’s stored for long time without electrify. The sensors need to be warmed up before use to achieve internal chemical equilibrium, the storage time and the corresponding warm-up time are recommended as follows： Table 9. Storage Time Suggested aging time Less than one month No less than 24 hours No less than 48 hours More than six months No less than 72 hours Cautions 1. Following conditions must be prohibited 1.1 Exposed to organic silicon steam Sensing material will lose sensitivity and never recover...
