DDS offer sulfur dioxide sensors in both our compact 32 mm and miniature 20 mm diameter ranges. Our sensor focuses on the five components of the Environmental Protection Agency’s Air Quality Index: ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrous oxide. After some initial discussion with our engineers, we supplied Mr. Feraco and his students with K30 10,000ppm CO2 sensors to create data loggers for the research projects. The sensor outputs current proportional to the concentration of NO 2. The MICS 2714 and the NO2 part of MICS 4514 both need preheating. This device is intended to provide the user with a cost-efficient means of determining air quality. It is important to know that it is not possible to combine the different groups of sensors (Single, Double and PRO). Company. If you have hardware that uses an MiCS-2710 and you need to replace the sensor, this module can be a drop-in replacement as the specs of the two sensors are nearly identical.
