Active collector set up on greenhouse roof. Strands and active components were acid cleaned using 10% acid stored in greenhouse lab and using a small soaking container for the parts.
The system triggered overnight but was off when I arrived at 10:45 am this morning. RH seemed to be reading accurately at ~65%. There was no sample and no wetness in the collector.
No tipping bucket is connected to the MIT mesh collector, only the optical rain sensor.
