The Apple AirTag is great for keeping track of things like your keys, bags, or even your pet’s collar. It uses Apple's 'Find My' network for that.
As for the battery life, according to the manufacturer, it should last about a year with normal use. It uses a CR2032 coin cell battery, which you can replace yourself. From our research, people generally find the battery life to be pretty solid, so you won't have to change it out too often.
Regarding weather durability, the AirTag is IP67 rated. This means it can survive being submerged in water up to a meter deep for about half an hour and is protected from dust, which makes it pretty durable for outdoor use.
However, do keep in mind that it won't tell you the temperature, like a dedicated weather sensor would.
So, if you're looking for a device just for tracking temperature, the AirTag might not be the best fit. But if you need a reliable tracker for your items, especially if you're already in the Apple ecosystem, it's definitely worth considering.
If you need both tracking and temperature monitoring, you might want to look into pairing the AirTag with a device that focuses on temperature readings.
