· 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 …
Add on the Direct Advantages. Do not forget that carbon monoxide alarms can be great life savers. Especially those which have smoke detectors integrated within the device itself.

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.
