I can’t even begin to tell you how many times I wished my phone had a built-in thermometer.  Sure, my skin can tell me when it’s too cold or too hot, but that’s hardly practical during the planning phase.  And yes, I could easily look up the weather report for my area, but I live close to the beach and we’ve got something called microclimates, so it’s hardly accurate.  Plus, the immediacy of being able to resolve temperature arguments with friends about how cold it is right then and there would be invaluable.

Enter the Thermodo.  It’s a Kickstarter campaign that has already blown the doors off their funding goal by $150,000 – they were initially looking for $35,000 to get things rolling and they’ve amassed over $180,000 in cash.  The Thermodo plugs into your iPhone or Android device’s headphone jack.  Leveraging the device’s battery – the Thermodo is a passive device – it is able to capture the temperature and then send that info via audio signal whereupon an accompanying app deciphers it.  And then presto, you’ve got a realtime temperature reading on your iPhone, iPad, or Android handset.

Thermodo consists of a passive temperature sensor built into a standard 4 pole audio jack enclosed by a sturdy housing. This allows your mobile device to read Thermodo’s temperature straight from the audio input. Thermodo sends an audio signal through the temperature sensor. This sensor will then attenuate the signal amplitude depending on the actual temperature.

The Thermodo is housed inside of a key ring receptacle, which should mean it’s always a finger or hand’s reach away.  Expect the Thermodo to ship sometime in August.  For some extra scratch ($39 vs $25) you can get one with an anodized aluminum finish.

Grew up back East, got sick of the cold and headed West. Since I was small I have been pushing buttons - both electronic and human. With an insatiable need for tech I thought "why not start a blog focusing on technology, and use my dislikes and likes to post on gadgets."
