Defective Adafruit PMSA003I

Post by sellitus »

Hey ya'll,

I just recently got a lot of cool sensors, including the PMSA003I, and all of them seem to work okay except for the PMSA003I air quality controller. Basically I have a UM Pro-S3 hooked up to only the air quality controller through the STEMMA connection, and after 1-2 minutes of running the air quality controller always stops sending information over the serial connection. Sometimes it will also cause the connection to my computer to disconnect, if I have it connected to the computer.

Any ideas what may be wrong here? Thank you in advance!

Are you seeing that behavior running the example sketch from the library?

Yes, sorry I should have included that information. I am just running the example Arduino application with no modifications (the same exact one you linked)

And just to verify the hardware setup - it's one of these:

connected to one of these:

via a STEMMA QT cable:

and nothing else it attached?

And then you are just watching the Arduino Serial Monitor output while the sketch is running?

Yes those are the exact right parts that I have wired up. And yes I am just monitoring the serial connection through the Arduino IDE

Also just wanted to add that I've tried other stemma cables too, but still have the same issue. Also I recently got a FeatherS3 and tried with that board too, with the same results

Do you have a non-ESP32 based board that could be used to run the same test? As a way to see if it's unique to ESP32.

Unfortunately I don't, I'm brand new to all of this stuff

Any additional help on this? I'm looking to return this sensor if it's defective.

Hooked one of these up to a Feather ESP32-S3 to test the basic setup and it's been running OK for well over an hour now.

The fact that the drop out also causes a disconnection from the computer seems odd:
Sometimes it will also cause the connection to my computer to disconnect
Is there anything else connected to the setup? How is everything being powered?

Very odd. I'm powering everything from the USB connected to my laptop, which seems to have no problem powering all the other sensors I have (including when 4 are hooked up at once). Nothing else is connected besides the air quality sensor through the stemma QT cable

Can you provide more details on what is happening with the board disconnects from the computer. Does the COM port completely go away? How do you re-establish a connection?

Good news! I hooked up the PMSA003I sensor (with other sensors connected too) and fired up the example PM25_test so I could give as detailed of a response as I could, and it has been running totally fine with no issues. I traded out the cable I was using to connect the PMSA003I to the UM PROS3 and tried to do everything I could think of to replicate the problem but I haven't been able to recreate the issue since the few times I had the issue before.

Sorry for the trouble. I'll follow up if I figure out what caused the issue, or if it happens again, but as of now it seems to be running great!
