Thermal image of a hot iron block
Infrared temperature sensors like the one listed here, has been interfaced to an analog to digital converting circuitry and in turn connected to Raspberry Pi. A processing sketch that runs on RPI acquires the signals from the infrared sensor and maps it as an image with different intensity of gray shades to indicate with area is hot and which area is cold. the image displayed by the processing sketch shows shades of gray, where black indicates a hot area and white indicates a cold area. Shown on the left is one such output images obtained as a result of scanning a block of iron heated from one end. The output image shows that the bottom part of the iron is hotter than the top part. Thus thermal imaging is possible on RPI..!! Come on, it is such a small task for RPI..!
