PS-VOC-lOO Air Quality Module Brief Introduction PS-VOC-lOO air quality module, works on the proven fuel cell technology, combines solid electrolyte with noble metal catalyst, converting VOC content into PPM directly. Once VOC arrives at working electrode (anode) it is oxidized instantaneously to generate an electrical signal. The electrical signal is then acquired and processed by microprocessor into a PPM value and is output by standard digital signal. PS-VOC-lOO is pre-calibrated in the factory and can be integrated into your system directly. Key Features High stability Good consistency Long...

PS-VOC-lOO Air Quality Module Technical Specification MODEL Module makes use of serial communication. Communication configuration parameters are:

6 PS-VOC-lOO Air Quality Module Baud rate > Communication Command There are two communication types: active upload type and Q&A type. The default type is active upload and it sends gas concentration once every second. Commands are as follow:

PS-VOC-lOO Air Quality Module PS-VOC-lOO Air Quality Module Gas concentration = concentration (high byte)*256 + concentration (low byte) ‘Function name: unsigned char FucCheckSum(uchar*i,ucharln) ‘Function description: checksum calibration[Take Not(Byte1+Byte2+...Byte7) +1] > Avoid moving or changing electronic elements on PCB. > Avoid exposure to organic vapour, organic solvents high gas concentration.
