The Kalt Sensor is a small accessory for your smartphone or tablet that is able to turn it into a precise non-contact infrared thermometer. The device plugs into the headphones jack of your iOS or Andorid device and after you install a dedicated application you are able to measure the temperature of various objects around you. The Kalt Sensor essentially reads the infrared energy that the object emits and translates that in user readable temperature of your choice in either Fahrenheit, Celsius or Kelvin. So by adding this sensor to your mobile device it will become much like those portable gun-like infrared thermometers sold at hardware stores. The project was successfully crowdfunded on Kickstarter raising $11100 USD with 217 backers, but if you missed to back it up then you can pre-order your sensor from the official website. The product is available in two main versions – with normal and with extra range sold for $43 and $48 USD respectively as well as in 4 different case colors and with an optional extension cable.

Kalt Sensor Specifications:
– High accuracy of 0.5°C over wide temperature range
– -70 to +380°C for object temperature
– Field of view 90 degrees (2:1 ) for normal model
– Field of view 35 degrees (6:1) for extra range model
– Displays the temperature in large , easy to read numbers
– Emissivity: 0.1 to 1 selectable from the app
– Response time less than 400 msec

What is important to note when choosing between the normal and extra rage model is the distance and size of the objects you are going to be measuring most of the time. The normal range model is for measuring larger objects from close distance due to the low ratio it has, so for example form 2 centimeters distance you will be measuring the temperature of a surface of 1 centimeter. The extra range version will allow you to measure the same 1 centimeter surface from 6 centimeters distance, or about 0.33 centimeter surface area from 2 centimeters. So make sure you have this in mind when deciding between the normal and extra range version.
