  • CO, CO2, and SO2 detection based on functionalized

    Sep 01, 2020The density of states of AGNR-O-OH before and after the adsorption of CO, CO 2, and SO 2, respectively, are shown in Fig. 10(a) – 10(c). By comparing the density of states of AGNR-O-OH with AGNR, three new peaks are observed around −23.3, −21.5 and 22.4 eV in the case of AGNR-O-OH due to the presence of -O- and –OH groups.Cited by: 3

  • At What Height Should Sensors be Mounted?

    1 min readThe sensor mounting height depends the type of application and on the density of the gas relative to air. Heavier than air gases should typically be detected 6 inches from the floor, lighter than air gas sensors should typically be placed on or near the ceiling, and gases which have a density close to that of air should have sensors installed

  • Selective SO2 detection at low concentration by Ca

    The gas sensing mechanism and high sensitivity of the La 1-x Ca x FeO 3 sensor towards the detection of SO 2 gas were explained by DFT (Density Functional Theory) calculations which give evidence for the strong binding of SO 2 molecules on the surface of the 121 planes of the sensor surface.Author: Chethana Aranthady, Teena Jangid, Kapil Gupta, Abhishek Kumar Mishra, S.D.

  • Altitude Compensation for CO2 Sensor Modules |

    A CO2 sensor calibrated at 400ppm at sea level would read 400(623/760) or 332ppm. Here at CO2Meter, our rule of thumb is that the CO2 level at altitude will change about 3% for every 1,000 feet (300m). At 5,000 feet, that would be 400ppm less 15%, or about 340ppm. This type of correction can have real-world consequences.
