Another interesting project from the same guys that brought the Lepton breakout board – Pure Engineering is the Lepton Demo Camera that can turn a FLIR Lepton thermal imaging sensor into a portable thermal camera. The project is basically a for the internals of a tiny digital camera that can take thermal photos onto a microSD card and view a live feed from the thermal sensor on the LCD screen. The FLIR Lepton Demo Camera kit comes without the Lepton thermal sensor, you need to source that separately. The camera kit is available from GroupGet at a price of $150 USD and minimum order quantity is 25 units – meaning that 25 people are needed to fulfill the group get too be successful. It is definitely an interesting project that will allow you to have a really portable battery-powered thermal imaging camera based on the FLIR Lepton thermal imager.

SparkFun has made available a new interesting development kit that allows you to get your hands on a FLIR Lepton thermal imaging sensor along with a breakout board specially developed for it in a single package that you can order. There are alternative ways in which you can get the Lepton thermal sensor such as a group buy or by purchasing a complete FLIR ONE Thermal Imaging Accessory for iPhone 5 and iPhone 5S and disassembling it to take out the sensor from it. But you also need to get the breakout board fr the sensor developed by Pure Engineering as well.

The FLiR Dev Kit offered by SparkFun has the breakout board as well as a the Lepton longwave infrared (LWIR) imager and is available for $349.95 USD, making it easy to get everything you need to start developing your own thermal imaging projects with an Arduino, Raspberry Pi or an ARM based development tool. Note that sourcing the sensor separately and the breakout board as well you could end up with a slightly lower cost, but it could take more time or efforts to get your hands on the hardware, so the SparkFun kit can be an interesting alternative if they have it in stock.

Besides the FLIR ONE thermal imaging accessory for iPhone 5/5S there is another product from FLIR that uses the affordable Lepton micro thermal imaging sensor – the FLIR TG165 Imaging IR Thermometer. Note that FLIR calls this device an Imaging IR thermometer, but it is essentially a low resolution thermal camera with a bit limited functionality. What the device does is provide you with a thermal image with a resolution of 80×60 pixels with a center spot meter report of the temperature that you point it at, so you get the best of both worlds – a thermal image for more accurate measurements and a precise infrared thermometer in once device. Unlike a traditional spot only infrared thermometer with the FLIR TG165 you can also save thermal images just like with a thermal camera. It is not as functional and feature rich as a full fledged thermal imaging camera, but for the price of $499 USD you can really get a very powerful device for measuring temperature accurately.
