Public Lab is an open community which collaboratively develops accessible, open source, Do-It-Yourself technologies for investigating local environmental health and justice issues.
Let’s talk about air quality data! Join us for Open Call on this topic every Tuesday until Dec. 14. Click here for details!
## Choosing Sensors
Often the first step is to look for a sensor for what you're hoping to measure. In the community posts below, we're collecting info on different kinds of air quality sensors, and their:
* links and documentation
Can you afford a sensor? Can it detect what you're looking for? Where can you learn more about it?
### Posts about choosing and evaluating an air sensor
### Expected ranges and useful detection limits for pollutants of interest
This [table](https://www.epa.gov/sites/production/files/2016-06/documents/air_sensors_webinar_slides_06-29-16.pdf) from an EPA [Air Quality Monitoring and Community Science webinar](https://www.epa.gov/sites/production/files/2016-06/documents/air_sensors_webinar_slides_06-29-16.pdf) lists the six criteria air pollutants and a couple additional pollutants, with background levels you might see in the environment in the “Range to Expect” column and useful detection limits for sensors.

+ Environmental consultant Tim Dye’s “[4 questions to ask before buying an air quality sensor](http://tdenviro.com/wp-content/uploads/2017/09/4-questions-when-buying-air-sensors.pdf)” neatly summarizes what to consider when choosing an air sensor.
+ [Snuffle.org](http://www.snuffle.org/): lots of information on low-cost sensors for various air pollutants.
+ [Air Quality Sensor Performance Evaluation Center (AQ-SPEC)](http://www.aqmd.gov/aq-spec/evaluations): from the South Coast Air Quality Management District, this program tests and evaluates air sensors “in the field, under ambient conditions, and in the laboratory under controlled environmental conditions.”
+ [Air Sensor Toolbox](https://www.epa.gov/air-sensor-toolbox): from the US Environmental Protection Agency, this toolbox includes guidance on how to use air sensors and their data, plus information on sensor performance and evaluation results. ...
