# Question: What different electronic particulate pollution sensors are available and at what cost?

I'm collecting some notes from across the site, including the #air-sensors and #particle-sensing pages in one place, and also interested in the latest updates on prices for different particulate air sensors. Thanks!

• The Speck uses a Syhitech DSM501A for ~$2 in quantity (thanks @chrisbartley !) • The Dustduino Uses a Shenyei PPD42NS available for ~$25.
• Here is a technical sheet for a $12.25 particle sensor by Sharp that can be purchased from here. The Sharp product works by detecting IR radiation that is scattered off the particles. The sensor outputs a voltage that is reported to be proportional to the concentration of particulates in the air. I have not seen code for this, but it looks like it would be pretty straight forward to write. Also note there are drivers for Arduino (see the comments!) + Raspberry Pi are available for the following devices: Log in to comment Just found this on my sunday net random navigation. At the core there's this sensor SKU:SEN0177 warren 23 days ago Interesting!!! Log in to comment The MiniVol is a few thousand dollars, i think used: https://publiclab.org/minivol but the samples cost a good bit to process (see page) And the ThermoFisher PDR-1500 is (used) I think ~$1500 -- https://publiclab.org/wiki/pdr-1500
