    I don’t know if this could inadvertently dox you but I’d be curious to see an hourly outside temperature too to see how much hotter a mailbox gets than outside. Based off your first graph here I’m wondering if cars having glass windows makes a greenhouse effect that would make a car hotter than a mailbox, everything else equal?

      Seems like a worthwhile thing to do! I’m not worried about doxxing, since someone would have to go to pretty extreme measures to correlate with the exact climate where I’m at. I installed the sensor after the hottest time of day had already passed, but here’s what it looked like:

      A graph showing the outside temperature versus the temperature in the mailbox.

      I’m pretty sure the spikes in the mailbox temperature were due to cloud cover.

        In my opinion this pretty conclusively proves that you can’t make a mailbox lasagna. This is the graph I looked but for my previous statement:

        A graph showing the temperature the inside of a car can reach in the sun

        And it shows that a car can hit 130-140 at temps around what you posted. Which is so much wildly higher than what you posted I do have to assume cars have some sort of greenhouse effect going that mailboxes don’t

        Finally when you consider how much of the total volume of a mailbox a lasagna covers, I have to imagine that’ll slow heating down even more! Great work!

          As a follow-up, I have a new record temperature. Thanks, West Coast heat dome!

          Here’s with the ambient air temperature:

            Damn. Even with the crazy high heat you’re basically parking the food right in the danger zone for bacteria growth. Mailbox lasagna: busted
