If you've ever needed or wanted to check out where heat is coming into or escaping from your house, there is a new iPhone attachment that does that. The company that makes it is called FLIR (Forward Looking InfraRed), and the iPhone attachment is called the flirone. FLIR has been around for a while now and they are the "go to" company for all things thermal imaging. They build devices that help to image household temperatures. Those are temperature between 32 degrees (Freezing point or water) and 212 degrees (Boiling point of water). This type of technology is crucial in troubleshooting heat loss or heat gain problems with architecture. They also help the medical professions see abnormally hot or cold areas of the body. Unfortunately these devices are usually astronomically expensive. However, the Flirone comes in at around $350.00 US. This is practically a steal based on what thermal imaging cameras usually retail for. Read more about it here.
