I am having a similar experience using AQ software 7.0 b007. I started experiencing this when I moved the monitor outside and placed under our pergola. It has been extremely hot here over the last month so I am wondering if this may be the cause. The pergola is partially enclosed and runs a couple of degrees hotter than outside.

I Ian,

If you already have upgraded your RX unit to v5.xx software, you could try the latest AQM software (v7.1_b004) which solves the NaN error.

Thanks Jim,
Things improve with the users feedback.
Now, any PM2.5 reading equal to zero, will not cause the NaN error anymore.

Werk,
Just uploaded b 004 and I am getting a zero reading for PM2.5 and PM10 and no NaN error but I don't believe the readings are zero; have never seen a zero reading in my location.

Code:

   WeatherDuino 4Pro
Air Quality Monitor v7.10 b004

Please wait...


Waking up the PMS7003 dust sensor (40s)
Reading PMS7003 dust sensor...

PMS7003 readings:
PM2.5: 0.00 ug/m3
PM10 : 0.00 ug/m3
PM2.5_1H_Avg : 0.00
PM2.5_NowCast: 0.00

Regards

Hi Jim,

I also had never seen a zero reading, this is why I haven't prevented that possibility before.

Unfortunatelly I haven't any PMS7003 at hand. If I had, I would have written a simple test software for the PMS7003, that will try to read the sensor at each 10 seconds, reporting the successful and failed attempts. That could help in you to understand those zero readings.
Anyway, even without the sensor I will try to write it.

Hi Jim,

Perhaps the attached software will help.
It tries to read to PMS7003 every 15 seconds. Output on the serial monitor.

Werk,
Thanks, how do I run it

Hi Jim,

If you give a look at the code you will see that just one line of code need to be uncommented.  Anyway I updated the software posted two topics above... now it should work without any editing.

i Guys,
I am now having the same problem in that my sensor when running in the AQM is reporting zero values. When i run the test software i do get readings from 2 to 6. Any ideas ??
