Txog Daim Ntawv Thov

Cov kab ke IOT no yog Kev Lom Zem Hauv Tsev thiab Kev Ruaj Ntseg.

1. Kev ruaj ntseg

   1. Coj mus rhaub daim npav RFID thiab cov tswv yim raug cawm hauv Firebase.
   2. Yog tias tau tso cai, koj tuaj yeem nkag mus tau zoo thiab daim duab raug coj thiab muab tso rau S3
   3. Yog tias tsis tau tso cai, ntu tiv thaiv los rau hauv thiab LCD Screen yuav hais tias koj tsis tau tso cai.

2. Kws muaj txuj ci

   1. Nias lub khawm ntawm lub dashboard.
   2. Laser Turrets yuav tawm tsam qhov tawg thiab nrawm.

3. Kev lom zem

   1. Yog tias pom cov lus tsa suab, qhov kev ua si yuav pib.
   2. Tom qab tus neeg siv ua si qhov kev ua si, cov qhab nia raug cawm hauv Firebase.
   3. LDR qhov tseem ceeb yuav raug coj thiab tso tawm ntawm lub dashboard.

Daim ntawv thov no tuaj yeem tswj hwm thiab saib tau ntawm IBM Node-Red web server. Peb siv AWS thiab IBM Cloud Services thiab peb siv Firebase ua peb cov ntaub ntawv.
