Adafruit_PM25AQI (Air Particulate Sensor) Library killing me

[RWB]

@ScruffR Saves the day again!

I learn the most from situations like this where you have to really dig in to get something working.

Here is another more advanced PM2.5 sensor that took quite awhile to get a working library for:

Sgp30 with sleep mode

I modified that code to send data to Losant instead. I also added the new particulate sensor SPG30 [image] My Losant dashboard is here for these sensors. https://app.losant.com/dashboards/599c9a05b36c040007c6e20c

Here is the library for that SPS30 Dust Sensor if you are ever interested in that one also:

Dust Sensor - PMS 5003/6003/7003

In March 2020 Sensirion has released a new version of the SPS30 datasheet. It shows that over the past year (or so) it has slip-streamed new firmware with new functions ( like sleep, wakeup, device status) as well as update / more information to existing functions. The SPS30 library (https://github.com/paulvha/sps30) has been updated to version 1.4. It does not only solve a couple of issues but mainly takes these new changes into account. Depending on the firmware level on your SPS30 you can tak…
