I need a CO2 sensor element for a project...price is important, and it should be able to read 0 to at least 5000 (and pref. Higher) parts per million. Analog or digital output would be fine, and I can temperature compensate it via other means, so don't necessarily need an integrated solution. Any leads welcomed :-) -marc -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
