Can anyone recommend a good add-on freezer temperature alarm?
I've got a small chest freezer in the garage that's a year old and
I have a lot of food in it, so i would like to know if the thing
quits for some reason.
One way to do it is with a home weather station. I have our freezer
as one of the stations on the weather station. I don't have an alarm
turned on, but I can if I want. My weather station (Oregon Scientific
from Costco) transmits to the Internet from the base console which is
hooked to the computer via a serial cable. With this setup I can
monitor my freezer temperature from anywhere in the world. Not that I
really need to. :-)
I would like to monitor environmental features (temperature, wetness, etc.)
remotely, in a commercial building that I own. Let's say there is an
always-on DSL internet resource in the building. There is one static IP
address associated with the internet subscriber's DSL modem. A firewall
router follows next, and links LAN computers to the internet. That firewall
normally blocks outside folks (like me) that might try to access a wetness
sensor attached to the LAN.
There is generally one port on the router that can be configured to operate
without firewall protection. I could put my sensor on that ("DMZ" i.e.,
DeMilitarized Zone) port.
How does your weather station connect to the internet?
