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

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.

Thermodo, 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.
