Here is a cool little gadget I'd never heard of before. It's a temperature datalogger. It lasts 60 days. Sadly I think it may be disposable (but I'd imagine rechargeable versions exist. )
Suppose you are shipping fruit across the country and you've paid extra to have the trucks chilled down to 65F. How do you know they didn't ship them at 75F and only lower the temp fully just before arrival?
Hide this bad boy in your shipment, then check the USB for data on arrival.

I had a similar sensor I was looking at to do experimental monitoring for a closed-ecology project. Because you could drop it inside, so you don't need to worry about connecting wires -- just take it out at the end.
But yeah, disposable/single-use.
I suppose it must have a coin battery inside. Could maybe figure out how to replace it?
@futurebird that’s really cool! I’m very curious what they’ve packed inside that lets them hit a price point of $4. Maybe a thermistor and some good wishes.
I'm fascinated by things like this for reasons I can't possibly articulate.
I almost bought one just to try it out and take it apart... but instead I'll just tell ya'll about it... I bet there are other interesting ways to use such a device. For example... you could detect if a chair is being sat in or not by putting it inside of a pillow...
@futurebird
Same!
So many things one could do with gadgets like that. Place them around the garden and house to see variation. Check the effect of those people who keep opening the fridge. See if the dog stays on its bed all night. See if my habit of venting the house in the morning and then closing up at 7:30 really does keep it cooler all day, etc.
I would like to see it miniaturized though. Swallow the thing and see temp changes as it travels
I've been using SensorPush since the crowdfunder; good stuff. Quite a few around the house and yard. The one sitting atop the thermostat makes me ask the same question as you with your freezer. Sometimes the thermostat just seems to lose track of what it's supposed to be doing!
Is your freezer one sitting out by itself? I have mine in a "thermal mass" so it rejects transients from opening the door, etc.
