Having fun with temperature sensors inside of bee hives. In the attached picture, BaitHive2, yellow, has more noise/static then the rest of the hives. I have replaced the sensor and confirmed that the problem is the bee's, not hardware. 🙂
I am not even sure how to ask this one. How would I extract the noise/static as a value? Something like signal to noise ratio, or standard deviation?
Here is my current search code:
index=beemonitor Temp AND HWID=* HWID=FE:FE:C5:0E:84:DC:AD:48
| regex _raw="HWID=\w\w:\w\w:\w\w:\w\w:\w\w:\w\w:\w\w:\w\w\sUUID=\w\w:\w\w:\w\w:\w\w:\w\w:\w\w:\w\w:\w\w\sTemp=\w*.\w*"
| where Temp > -55 | eval TempF = ((Temp*9)/5)+32
| timechart span=30m limit=32 eval(round(avg(TempF),2)) by UUID
