120x84 Thermopile Infrared Array
The HTPA120x84d is our highest resolution thermopile infrared array inside a TO-8 housing, which is best for thermal imaging.
Due to the digital SPI interface, only six pins are needed for operation. It has a 16-bit ADC and built-in EEPROM stores all calibration data. The framerate can be set individually and depends on the sensor clock and ADC resolution
For high 16-bit resolution, framerates of 9 Hz are possible, while lower ADC resolutions allow framerates of up to 30 Hz and more. Different available optical lenses, integrated with the array in TO-8 housing, provide fields of view (FOV) from 12x9 degree up to 120x90 degree.
The 120x84 array can be used as drop-in solution for the 80x64 array as it provides the same PIN-out and dimensions.
