MH Z14 CO2 ELETRO

Best way to detect vehicle exhaust? - Page 1

Apr 15, 2017· CO2 sensor is fairly cheap, I use the MH-Z19 and it is very good ($28). MH-Z14 is also available but oddly more expensive. From the link below, output of exhaust is 6-8% (so 60-80,000 ppm). The MH-Z19 range is 0-5,000ppm which should be fine, if you go above that level it will just clip at 5,000.
