Devices that enable the visualization and measurement of temperature variations across surfaces using an iOS device are increasingly available. These consist of an external camera that connects to an iPhone or iPad, interpreting infrared radiation emitted by objects to create a thermal image. For instance, building inspectors can use such devices to identify insulation gaps through temperature differences visible on a wall.
The utility of this technology stems from its ability to detect temperature anomalies invisible to the naked eye. This is beneficial in diverse sectors, from detecting electrical faults in machinery to diagnosing potential water leaks behind walls, thus preventing costly damage. Historically, thermal imaging was confined to specialized and expensive equipment; the emergence of iOS-compatible cameras has democratized access to this technology, making it more affordable and portable.
