Digital atomic wall clock showing the time of 7:04 PM, an outside temperature of 158°F, and humidity of 99% outdoors.
edit:
A replacement sensor is just over $20, but I found this (see below) for $15, so both my wall clock and the new one can read off the same new, full functional sensor. So now it’s fixed.
It’s weird that the new one does outdoor and indoor temp, but not humidity. The old one does outdoor temp and humidity, but not indoor temp. And the new one isn’t an atomic clock. I had to set it manually.
Unfortunately it’s time just came. I’d already opened it up and fixed it once before. There were buttons that were barely working, the battery connectors stopped working and it only worked with the power cable (the atomic feature wouldn’t sync from my bedroom and when I tried to move it to resync with the time change it wouldn’t hold the settings, even with new batteries), the screen was starting to get weird and I decided that it wasn’t worth it for a $20 clock that was over 20 years old when I have other clocks.
