PS-CO-5000 CO module, works on the proven fuel cell technology, combines fuel cell technology with precise electronic technique, converting the CO content into PPM directly. Once CO arrives at working electrode (anode) it is oxidized instantaneously to generate an electrical signal which is proportional to the CO concentration. The electrical signal is then acquired and processed by microprocessor into a PPM value and is output by standard digital signal. PS-CO-5000 is pre-calibrated in the factory and can be integrated into your system directly. Typical Applications Factory for Li Battery Charging...

Technical Specification Communication Protocol Module makes use of serial communication. Communication configuration parameters are:

Gas concentration = concentration (high byte)*256 + concentration (low byte)
