So I just did a quick smoke test on the PM sensor, and managed to get PM2.5 reading of 127.1 ̣µg/m³ and a PM10 reading of 152.36 µg/m³. The AQI was an unhealthy 187. The sensor appears to be working ok. On the next read 10 minutes later, the values had more or less halved.
I managed to get the CO2 meter reading to about 3000 ppm by breathing heavily on it, but it is very slow to drop down under 1000.
Perhaps it needs a good airflow around it. If tomorrow is dry I will run a mains extension lead out in to the middle of my garden and test the monitor readings there all day - I don't have an enclosure yet. Waiting for a lcd display to arrive which will make testing much easier as I wont need to be in range of the Pro2 plus receiver.
Thanks,
Heeby
