Product Number:  ADuCM360_demo_cn0338 

    		        		    		    	
			
To whom it may concern


I have a question regarding the different gas species detection by using the ADuCM360_demo_cn0338.


I know that there must be a specific filter for each desired gas species that I aim to measure but practically I do not know how to do that.


I would be grateful if you help me with that. My desire is to measure CO2, CO, and CH4.


Thank you in advance,


Sincerely,


Reza

    Hi Reza,
    

    Apologizes for missing this question.  So from a filter perspective that is actually done on the hardware level. Each sensor is designed for a particular wavelength, hence each sensor is going to be able to read a particular gas.
    

    What you would need to have a look at is the sensor which is currently included with the CN0338 and then find another sensor within that product family which could identify that gas and also fit into the same pins that are found on the EVAL-CN0338-ARDZ.  The bill of materials can be found here - www.analog.com/cn0338-DesignSupport and from there I would go to the sensor manufacturers website to find out which other gas sensors exist within that product family.
    

    Hope this helps,
    

    Cheers,
    

    Brandon
