Olu luyilo lwamkela i-AT89S52 uthotho lwe-microcontroller ukuqokelela, ukugcina kunye nokusebenza kwedatha. Ekubeni umqondiso unegalelo elilodwa kuphela, ukwenzela ukuba ugweme ukusetyenziswa okungadingekile, i-ADC0804 isetyenziswe kwi-A / D converter kule design. Iitheminali zetshiphu ze-CLKIN kunye ne-CLKR zinokuvalwa yitshiphu ngokwayo. I-sensor ye-pyroelectric esetyenziselwa ukulinganisa amandla akhanyayo omgangatho wento yi-PM611 ye-pyroelectric sensor evela ku-Nicela Sensor Co., Ltd., enokulungelelanisa ngokufanelekileyo ukuguquguquka kweqondo lokushisa kwimeko yangaphandle. Umboniso wamkela iityhubhu zedijithali ze-4 8-bit ze-LED. <br>Umsebenzi oyintloko wale sekethi kukuguqula amandla emitha ye-infrared efunyenwe yi-pyroelectric sensor kwi-signal yombane efunyenwe yi-A / D converter. I-tube yedijithali ye-LED iqhutywe yi-port ye-P1 kwaye ilawulwa yi-microcontroller ye-AT89S52 ukubonisa ubushushu bomhlaba bento. Ngokusebenzisa inkqubo yesoftware, ukuboniswa kwamanani amathathu abalulekileyo kunokufezekiswa. Ngaphantsi kwe-100 degrees, amanani amabini apheleleyo kunye nendawo enye yesishumi abonisiwe, kwaye ngaphezulu kwe-100 degrees, amanani apheleleyo amathathu ayaboniswa.
