Recent advances in graphene based gas sensors - ScienceDirect

· The sensor did not show any response to CO, NO 2 or CH 4 gas due to the selective filtration of H 2 by the polymer membrane coating on the Pd NP/SLG hybrid. Upon exposure to 2% H 2, this hybrid sensor showed sensing response of % within min and a recovery within min. The NO 2 detection behavior of organic thin film transistor (OTFT) based gas sensors employing …

CO2 Sensors Products |

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 0-1% (0-10,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.
