Laser pollution sensors by PurpleAir use laser particle counters that provide an accurate and low-cost way to measure smoke, dust, and other particulate air pollution. Laser air quality sensors with both internal storage and data-transmitting abilities.
The PurpleAir PA-II sensor is very reliable. Three years ago we deployed 25 sensors throughout our region and they are all still running strong with high confidence.

I ordered a sensor last year to get accurate air quality readings in my neighborhood. The sensor works GREAT, customer service is GREAT, and I have no complaints. Highly recommend this product and company.
