Today something interesting happened Here, we had high winds from the Egypt, which carried a lot of dust.
The result was a sharp change in the PM:
Feb 8 – PM was 2
Feb 9 – was 0.3
Feb 10 – was 3.7
I am validating the PM I query, so I won’t run the irrigation for ever in the case a bird builds a nest over the meteorological sensor.
So it emailed me today to tell me a sharp factor was found between the last day and today.
I adjusted the thresholds , and the system recovered.
