TinkerForge 278 Thermal Imaging Bricklet

The Thermal Imaging Bricklet is equipped with a 80x60 pixel infrared camera. The Bricklet can be connected to Bricks.

The Bricklet uses a FLIR Lepton sensor with radiometry and shutter. The sensor can measure temperatures between -10°C up to 450°C with a resolution of 80x60 pixels.

A spot meter can be defined to measure minimum, average, and maximum temperature for a defined region in the image.

The Bricklet supports two modes: High Contrast Image and Temperature Image.

In High Contrast Image mode, the Bricklet streams image data with 8.6Hz and 8 bit resolution. The image data are gray values, the high dynamic range of the sensor is combined to be suitable for display. This mode is used by thermal imagers available on the market. Usually, the gray values are mapped to false colors by means of a lookup table.

In Terperature Image mode, the Bricklet streams data with 4.5Hz and 16 bit resolution. In the image data, each 16-bit value represents a temperature between -10°C and 450°C with a resolution of 0.1°C or a value of -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 for the analysis of temperature changes.

The shutter is automatically controlled by the Bricklet.

The Thermal Imaging Bricklet has a 7-pin Bricklet connector and is connected to a brick with a 7p-10p Bricklet cable.
