Some commercial options

vendoritemnotes
PieraIPS-7100

https://pierasystems.com/products/piera-7100-intelligent-particle-sensor/

only $100 and unlikely to give the performance we need but does claim to give particle size histogram

Plantower

PMS5003

PA-II

https://www.plantower.com/en/products_33/74.html

https://pubs.acs.org/doi/epdf/10.1021/acs.estlett.3c00030 - does better (allegedly*) than IPS-7100 at <1 micron

*has been found to not always adhere to manufacturer guarantees

$200, best coefficient of determination found, leading competitor of Piera IPS-7100, used by Forest Service

It's the algorithm that puts this one so high

PieraCanaree R1

https://www.aqmd.gov/aq-spec/sensordetail/piera-systems---can%C4%81ree-r1

Great coefficient of determination, same manufacturer as IPS-7100, built for Ethernet, $300

FabLabSmart Citizen Kit V2.1

https://www.aqmd.gov/aq-spec/sensordetail/fablab---smart-citizen-kit-v2.1

Highest guaranteed coefficient of determination at PM1.0, $120

SensirionSPS30

https://www.sparkfun.com/products/15103

Cheap $50, similar performance to leaders


A potential non-commercial option from NASA is MPASS: https://technology.nasa.gov/patent/LEW-TOPS-19 → Could send them an email to see if it's an option for us.

March 1 2024. 
Ordered two evaluation kits of IPS-7100 through Newark:

Particulate Sensor Installation in AuxTel, 05/14/2024--Kane

Installed x1 of the above particulate sensors in the AuxTel dome. It is currently mounted (taped) on top of the mac mini that runs DIMSUM, and connected via USB A to C hub.

A better, permanent placement will be determined. 


The Mac Mini has the newest SenseiAQ software (v2.0.4) installed, and the software picks up the sensor, and is logging data as a .csv. 

Guide to connecting to Mac Mini via VNC, from non-Apple OS (Windows/Linux, etc)

  1. Download TigerVNC. 
  2. Configure the settings page as follows:
  4. With the above settings, now enter the address. The VNC connection address is:
  6. The connection password is the same as for the Mac Mini (not gonna put it here for the world to see).
