    Streszczenie angielskie: The breathing activity recorder uses three miniature thermistor sensors to detect a flow of air during inspiration and expiration. Changes in sensors, resistance with temperature are converted into voltage and digitized in a 10-bit A/D converter. Detection of the breath is done by microcontroller PIC16F877. Detection algorithm is based on the comparison of the actual signal amplitude with the threshold level. Samples of the signal are transmitted to a host computer via an infrared data link using a IrDA standard. A delicated receiver powered from computer port lines, converts a specific 10-bit data format to two 8-bit words in a RS-232 standard. Data displayed on the screen are stored in a simple database. The algorithm for detection of the breath is similar to that in a microcontroller, however is performed again on line on the raw data. Such a solution allows using much more sophisticated and precise computation than that applied in a simple 8-bit processor unit.
