Vantage Vue ?Failing Humidity Unit?
Posted: Thu 26 Aug 2021 4:22 pm
My ageing (10 years old) Vantage Vue seems to be having a problem with it's Temp/Humidity/WindSpeed module.
5 years ago (or thereabouts) I replaced this sensor PCB due to erratic Temp and Humidity values.
The attached two graphs show the humidity readings for the Vantage Vue and my much newer GW1000 / WH65 (7 Sensor Unit).
The GW1000 seems to be correct in that the humidity increases at night as the air temp falls.
The Vantage Vue shows a drop to virtually 0% humidity as night time approaches and come back again in the morning. All other sensors / values with the VV are in good agreement with the WH65.
The last time I had the problem the temp was displaying as -40C and when I opened the ISS unit up it was absolutely soaking wet inside due to excessive condensation - it was November here in the UK and we get very heavy dew / frosts but NOT -40C !!
So I guess it's the same fault - but caught a little bit earlier - however I don't seem to be able to source a replacement PCB - I don't think Davis is making them for this age of Vantage Vue.
Anyone no any better? Here's hoping
