Kev Ntsuas Kub Siv Esp32 thiab Thingsio.ai Platform: 6 Kauj Ruam

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Hauv qhov kev qhia no kuv yuav piav qhia txog kev ntsuas qhov ntsuas kub hauv ib puag ncig los ntawm kev siv lub ntsuas ntsuas qhov ntsuas sov tam sim no hauv esp32 kev txhim kho pawg thawj coj. esp32 muaj ntau yam inbuilt sensors zoo li lub sensor sensor siv ua qhov sib thooj sensor, kov sensor, ntsuas kub. Hauv qhov kev qhia no peb yuav tham txog qhov ntsuas kub.

Kauj Ruam 1: QHOV TSEEB:

Kho vajtse:

1.esp32 pawg thawj coj loj

Software:

1. Arduino IDE

2. Thingsio.ai
