The Bricklet uses a FLIR Lepton sensor with radiometry and shutter. It can measure a temperature range of -10°C up to 450°C with a resolution of 80x60 pixel.
A spotmeter can be set to measure the minimum, mean and maximum temperature of a user defined region in the image.
The Bricklet supports two image modes: High Contrast Image and Temperature Image.
In High Contrast Image mode the Bricklet provides an image stream with 8.6Hz and 8 bit resolution. The image data is grey-scale, the high dynamic range of the sensor is collapsed to be appropriate for display. This mode is used in thermal imaging cameras that are available on the market. Typically the grey-scale data is converted in a pseudo-color image by a lookup table.
In Temperature Image mode the Bricklet provides an image stream with 4.5Hz and 16 bit resolution. In the image data each pixel represents one 16 bit temperature value between -10°C and 450°C with a resolution of 0.1°C or a value between -10°C and 140°C with a resolution of 0.01°C (depending on the resolution configuration). This mode can be used for scientific calculations and to analyze absolute temperature changes.
The shutter is automatically controlled by the Bricklet.
The Thermal Imaging Bricklet has a 7 pole Bricklet connector and is connected to a Brick with a 7p-10p Bricklet cable.
