[wxqc] Davis and Power Outages

[Dave Helms]

RE: Davis and Power Outage

The Davis VP2 wireless units' console has a battery backup while the 
sensors have solar and battery backup allowing it to keep collecting 
observatiobs for several hours without commercial power.  The Davis 
WeatherLink memory module will store data for weeks until you are able 
to sync the module with the WeatherLink application on the PC.  All and 
all, the Davis system is very robust/resistent to commercial power outages.

The trick for most folks is to keep uploading data to NWS is keeping the 
PC CPU and cable/DSL modem going on generator or UPS during the power 
outage.... that is the weak link in the process!
