Thermodo from Robocat Measures Ambient Air Temperature Using the iPhone's Headphone Jack

by

Robocat, the Danish software studio behind apps like Haze and Thermo, has launched a new Kickstarter project for a small thermometer that can be plugged into the headphone jack of a smartphone or tablet to measure indoor and outdoor temperatures.

You can measure the temperature indoors as well as outdoors. Track the temperature and see how it rises after you turned on the radiator or check how the temperature drops during a summer night. No network connection required. Thermodo comes with a neat little keyring so you'll always have it with you.

thermodoThermodo, which comes with a cap and a keyring, functions with a custom companion app in addition to Robocat's already existing weather apps. The studio will also release an SDK, allowing other developers to create apps that work with the device.

The miniature thermometer comes in black, white, and a premium anodized aluminum version available through Kickstarter. It measures temperatures in the range of –20 °C to +50 °C (–5 ºF to 120 ºF).

Backers can get a Thermodo device for a $25 pledge, or the premium version for $39. The company has already met its Kickstarter goal of $35,000 and plans to begin full production in July, with an estimated shipping date of August.

Could I connect it to an 3.5mm audio extension cable? Then I could run the cord from outside to my bedroom and plug in the extension in the morning to see the temp outside. THAT would be cool.

Or you could buy this

This one has a whistle AND a compass.
Best of all it doesn't draw power from your laptop

I don't know about others, but I use weather data in passing. Meaning, I really don't care what the exact temperature is. As long as I can get the ballpark number, I'm fine. I don't spend more than 15 minutes per year inside a weather app probably, and I'd spend even less plugging and unplugging this thing in my iPhone/iPad.

Elgato has the "eyetv mobile (http://www.elgato.com/elgato/na/mainmenu/products/EyeTV-Mobile.html)" (that's the U.S. version, for most other countries you'd need this version (http://www.elgato.com/elgato/int/mainmenu/products/tuner/EyeTV-Mobile12.en.html)).
That device only receives TV signals from the Dyle network (http://www.dyle.tv/).

The signal of the Dyle network looks spotty and it sounds like they will start charging a fee to use it in 2014.

Is there a subscription fee for Dyle mobile TV?
Dyle mobile TV is available with no subscription fee through the end of 2013.

I will wait for something that receives an ATSC signal like an HD Television does.

I like the idea of peripheral devices that make use of iOS devices without needing Internet... Cause sometimes there isn't Internet...for example tomtom is a great app that uses GPS without absolutely needing Internet...

1 peripheral I woul love to invent if not already out there is a peripheral plug in that picks up local tv...perfect for storms etc that wipe out cable Internet and tv

I can't imagine why you wouldn't be able to.

How accurate is it? And -5F seems like an awfully high lower limit... How cold can my iPhone get while I use it?
