2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Txais tos! Qhov haujlwm Raspberry Pi no yog "lub tsev ntse" kev tswj hwm, uas tuaj yeem ntsuas ntau yam ntaub ntawv xws li ntsuas kub, av noo thiab teeb pom kev zoo ntawm ntau qhov chaw hauv tsev. Cov lus qhia no yuav npog kev teeb tsa nkag mus thiab chav nyob nrog rau 1 chav pw.

Cov ntaub ntawv raug xa tawm thiab ua tiav los ntawm IBM Bluemix ua ntej yuav raug xa rov qab mus rau Node-Red, thaum qhov ntawd ua tiav cov haujlwm tsim nyog xws li tig lub teeb thaum tsaus ntuj thiab pom cov lus tsa suab.

Cov neeg siv tuaj yeem saib cov ntaub ntawv sau los ntawm Dashboard hauv Node-Liab uas qhia txog qhov ntsuas tam sim no ntxiv rau cov duab sawv cev ntawm qhov ntsuas thiab daim duab keeb kwm. Lub Dashboard tseem suav nrog cov yam ntxwv ntxiv xws li lub moos uas qhia txog cov ntaub ntawv tam sim no thiab sijhawm thiab hloov mus rau kev tswj hwm ntau yam khoom siv hluav taws xob, uas tau sawv cev ua LEDs thiab lub suab nrov.

Thaum kawg, muaj lub tswb nrov hauv tsev suav nrog MFRC 522 RFID daim npav nyeem ntawv, lub suab nrov, lub suab ntsuas thiab 16x2 LCD zaub. Qhov xwm txheej ntawm RFID lub tsev tswb ceeb toom kuj tseem tshwm ntawm lub dashboard. Dab tsi ua rau lub tswb ceeb toom hauv tsev tshwj xeeb yog tias nws tuaj yeem nyeem cov lus muab rau nws xws li "Zoo Siab Txais Tos Tsev" los qhia tias tau txais kev nkag mus lossis "Access Denied" los qhia tias kev nkag mus tsis raug. Thaum muaj qhov ntsuas pom thaum lub teeb raug kaw, lub suab nrov yuav nrov nrov thiab email yuav xa mus rau tus neeg siv. Thaum lub tswb raug tso tawm lwm tus email yuav raug xa mus.
