Hello guys,
I have joined in the community just a minutes ago.
I’m looking for suggestions on Particle sensors which provides the data on MC & NC of PM1.0, PM 2.5, & PM10.
Previously, I have worked on Sensirion SPS30, Cubic PM2008_M, Cubic PM2012SE_R, Plantower PMS9003. I had problem working all this sensors.
Sensirion SPS30 - Giving a good of only PM2.5 and the remaining channels of PM4.0, PM10 are giving the same exact values of PM2.5.
Cubic PM2008M_M & PM2012SE_R - These sensor are showing 0 for every channel when ever the concentration is < 80-90 µg/m3, and also some wierd sharp raise in the MC of PM for every 2 hours shift.
Plantower PMS9003 - This sensor it is showing all PM values as 0. I have bought four of them all showing the same readings.
I would request your help in suggesting me some good particle sensors which provides a good data on PM and all channels working indepently to each other.
Hello,
I'm using Grove SEN5X All in One from SeeedStudio. I can't know how accurate the readings are, but as you see from the screenshot they are not identical which is a good sign. These and the VOC do react quite quickly when I'm using a toaster, frying food, using the fireplace etc. Even the robot vacuum is causing them to react when nearby.
@ARa, just to be clear, Particle does not make or sell sensors. Instead, they make the wireless platforms on which you can build IoT devices using various sensors for personal and commercial use. Regardless, as you can see from @ThomasV's post, this community is very supportive!
Hello ThomasV,
Firstly thank you for your suggestion.
But, here in the data sheet of sensirion SEN5X they have mentioned that PM4 and PM10 were calculated based on distribution profile of all measured values. So, these channels were not independent really.
So, if I understand that sentence in the datasheet correctly, they use a predefined distribution profile for PM4 and PM10, based e.g. on PM1.0 and/or PM2.5. Leading to, as you wrote, that the sensor does not explicitly measure PM4 and PM10? For my purposes as a hobbyist it does not really matter that much, but for professional and scientifical purposes it obviously matters.
