Dab tsi yog lub tshuab nqus pa uas koj tuaj yeem nug? Nws yog ib qho cuab yeej ntsuas kwv yees cov ntshav cawv (BAC) los ntawm cov pa ua piv txwv. Hauv cov lus yooj yim nws yog cov cuab yeej ntsuas huab cua tus neeg haus cawv lossis tsis haus cawv. Raws li lub npe qhia tias nws ua haujlwm ntawm arduino. Pur peb lub tshuab nqus pa siv MQ-3 cawv los ntawm lub suab nrov. lub tshuab nqus pa hauv ib lub thawv, thiab ua qee qhov kev hloov pauv rau koj lub tshuab nqus pa. MQ-3 tsis raug txaus los sau npe BAC tseeb thiab nkag siab rau qhov kub thiab txias. Tsis txhob haus dej thiab tsav tsheb thiab yog tias koj hu kuv = D.

Peb yuav siv 7805 5v tus tswj hwm coj mus rau 9v los ntawm lub roj teeb thiab muab qhov ruaj khov 5v rau MQ-3 cawv ntsuas peb ua qhov no kom MQ-3 tau txais lub zog txaus (<750ma). Yog peb txuas MQ- 3 ncaj qha mus rau arduino, muaj kev phom sij ntawm kib nws. Kuv siv ib leeg 1000 uf capacitor nrog 7805 tus tswj hwm kom muab 5v. Kuv tsim 5v khoom ntawm lub rooj sib cais ntawm Circuit board koj tuaj yeem siv tib lub rooj sib tham ntawm qhov uas peb Kuv tab tom txuas lub tshuab hluav taws xob kom lub tshuab nqus pa tuaj yeem qhib lossis kaw tau. Saib daim duab kawg rau daim duab qhia chaw. tag)

Breathalyzer Microphone: Lub tshuab nqus pa microphone yog lub kaw lus tsis sib xws ntawm cov ntshav-cawv cov ntsiab lus qib cov ntaub ntawv teev tseg. Hauv lwm lo lus, koj tuaj yeem ntsuas tus neeg qhov tsis txaus ntseeg nrog lub cuab yeej, uas rau txhua qhov kev xav thiab lub hom phiaj, zoo li tsis txawv li sawv ntsug
Breathalyzer Medallion: 4 Kauj Ruam (nrog Duab)
Breathalyzer Medallion: Peb txhua tus muaj tus phooj ywg tshwj xeeb uas xav tau kev saib xyuas thaum hmo ntuj. Kuv hu ua Geoffrey, thiab nyob rau nws lub asthiv tas los nws zoo li ceev faj kom muaj qhov pom sab nraud ntawm qhov kev lav phib xaub nws yuav zoo li cas
Cov Duab Duab Duab thiab Cov Duab 1: 4 Cov Kauj Ruam (nrog Duab)
Cov Duab Duab Cubes thiab Cov Duab 1: Thaum sim nrog qee cov ntoo ntoo thiab cov duab los qhia, kuv pom ob peb txoj hauv kev los ua cov voos thiab lwm yam duab los ntawm cov khoom siv yooj yim. Los ntawm kev muab cov no los ua Cov Ntawv Qhia, Kuv vam tias yuav txhawb nqa kev ua si thiab kev kawm. Kev hloov pauv ntawm qhov kev qhia no
