All Rights Reserved.We've made some changes to EPA. Emerging air quality sensors — with general traits of being more compact, directly reading pollutants, and lower in cost than traditional methods - have a wide appeal to professional researchers, community groups, students, and citizen scientists alike. Since this technology is still under development, little information exists on the quality of data that these sensors produce.
To help those interested in using sensors as part of air monitoring projects, EPA researchers evaluate sensors for how well they measure air pollutants and how easy they are to use. Placing the sensors near a regulation grade monitor, researchers collect data on air quality with both technologies. By assessing these data collected under the same air quality and weather conditions, researchers can compare how accurate and reliable low-cost technologies are to traditional methods.
The following air sensors have been evaluated in laboratory or field studies by EPA researchers. To assist the user, Sensor Evaluation Tables have been created that provide selected sensor performance results from reports, which can be found on the Air Sensor Toolbox.
Note that the results provided in these tables are a subset of all of the sensors and tests conducted, some results are not shown in these summary tables for sensors that had inconclusive results due to either data logging failure, reference monitor failure, or other limiting factors. The full information on all test results are available in the full-length reports.
EPA researchers continue to test sensors in various field or laboratory studies, and emerging results will be added to these tables over time. Any mention of trade names or commercial products does not constitute endorsement. Note that cost information is not reported here, as the market prices of sensors are at the purview of the manufacturer or distributors, and may change with time or purchasing volume.

Other sensors such as the particle sensor are essential in ensuring compliance with emissions requirements. The particle sensor was developed for use both in passenger cars and commercial vehicles with an adapted sensor control unit SCU. The sensor is installed downstream of the diesel particle filter and can be installed quickly and easily thanks to a retaining screw.
The functional principle behind the particulate matter sensor is based on resistance measurement. Soot particles are deposited on an electrode structure and form conductive soot trails between the electrodes. Prior to each measurement phase, the sensor element is regenerated through heating so that the sensor element adopts a defined status before the start of the measurement process.

Product details. Need Help?This project uses a Honeywell HPM series particle sensor to measure and display 2.
Particulate matter PM is defined as the combination of solid particles and liquid droplets found in the air. Some particles are large enough to be seen with the naked eye while others are microscopic.
Very small particles are of particular importance as these can be readily inhaled. When inhaled concentrations are large enough and exposure is long enough, they are linked to adverse health effects.
Particle sensing, PM2.5, pollen, dust
For air quality, particle sizes are frequently grouped into two categories: those smaller than 2. The standards are expressed as a function of particle concentration and exposure duration e. PM in our environment comes from many different sourcesincluding man-made and natural processes. In this project, we will use a Honeywell HPM series particle sensor to measure and display PM concentrations in sampled air. PM monitoring has a variety of industrial and consumer applications including general air quality measurement as well as specific relevance to processes associated with heating, ventilation, air conditioning, air filters and air purifiers.
The sensor is an integrated unit that contains a laser light source, detection chamber, photodiode, exhaust fan and a communications interface. Particles are counted using the light scattering method. An internal laser light source illuminates particles as they are transported, via the air inlet and the exhaust fan, through the detection chamber.
Particles obscure the light and change the electrical activity of an internal photodiode. That activity is analyzed and converted to a particle concentration, which can be transmitted through the serial interface. The device accepts the seven commands as listed below and detailed in the device datasheet PDF. Based upon my evaluation, the following default conditions are used on power up, regardless of any subsequent changes; the internal fan is turned on, Auto Send is enabled, the Customer Coefficient value is Changes made after power-up are volatile and are not saved internally i.
