Kuv siv lub ntsuas no ntawm 2 ntawm kuv cov neeg hlau. cov ntawd tau ua haujlwm saum lub rooj, yog li cov neeg hlau yuav tsum kuaj xyuas thaum lawv tuaj txog ntawm ntug, kom nres, thiab tig rov qab …

Kauj Ruam 1: Tus Qauv Yooj Yim Nrog Bipolar Transistors

Ib qho yooj yim Version Nrog Bipolar Transistors

ua ntej kuv ua qhov yooj yim version nrog bipolas transistors. tag nrho cov lus qhia ntawm tus neeg hlau me me tau txuas nrog (tsis yog tib neeg hlau zoo li nyob rau nplooj ntawv tom ntej).

lub ntsiab lus hauv kev ua haujlwm yog: 1. tus oscillator tsim lub voj voos xwmfab. 2. ib qho infrared coj nrog lub kaum nqaim kis lub teeb liab no ua lub teeb ci/duab hluav taws xob. 3. qhov no yog xav rov qab los ntawm cov teeb meem sab hauv lub kaum ntse ntse saib, qhov tseeb los ntawm qhov pom ntawm qhov chaw hauv av, lossis nyob rau pem hauv ntej ntawm tus neeg hlau. 4. muaj lub photodiode lossis phototransistor nyob ib sab ntawm IR-LED, nrog rau lub kaum nqaim taw qhia rau tib qhov chaw ib yam li LED tau. phototransistor tau siv ntawm bipolar version, thiab photodiode ntawm IC version. 5. muaj lub receiver Circuit txuas nrog lub sensor, kuaj xyuas yog tias muaj teeb pom kev zoo lossis tsis yog. 6. yog tias muaj lub teeb liab (hauv qhov tshwj xeeb zaus band, zoo li 5khz-150khz), tom qab ntawd cov ntawv tso tawm mus rau qhov laj thawj siab, txwv tsis pub qis dua. lub teeb liab no tuaj yeem siv los ntawm lub microcontroller, lossis los ntawm kev sib piv kev sib piv muaj lub teeb liab yog tias muaj qhov cuam tshuam/hauv av hauv qhov kev nkag siab, uas yog li 5-15 centimeters.
