does it work in very cold weather, negative degrees

We live in Texas. It was fine for 4 years until our first cold front came in 2 weeks ago. We went down to 60 F when the sensor stopped working. I ordered a new sensor with amazon. That one stopped working after 3 days when the next cold front came in at 55 F. What a terrible waste of money. I'll be calling La Crosse on Monday.

Hi Linda. Mine appears to be within 1°F. Plenty good enough to monitor the weather. As a standard, I have a 14" Fisher mercury in glass laboratory thermometer accurate to 1/4°F, which I trust. I use two display stations (upstairs and downstairs) running off one outdoor transmitter. They both read exactly the same at all times and are now about 2 years old. Hope this is helpful. Don

What is the thickness measurement of the outdoor sensor? I live in an apartment and must place it between a window and a screen.

Here are the measurements: 3/4" (at 'hanger' end) to 5/8" thick (main body of sensor). it is 5" high and 1.5' wide. It would certainly fit between the window and the screen; however, my husband says you may not get a true temperature reading because it would pick up the heat from the window even though it is outside. Can you put it on the window sill on the outside of the screen? That is where I have ours and it works fine. Has not fallen off our brick window sill even though it is slightly slanted. Hope this helps....

can you hang from wall?

Yes. It has a slot with a hole in the bottom, (sort of like an upside-down keyhole) to slip over a screwhead and slide down to hold in place. Sorry about the description, hope it isn't too confusing. In short it would be very simple to hang on a wall.
