Av Ntsuas Cov Ntsiab Lus Ntsuas 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 nyeem cov dej noo hauv cov av los ntawm kev siv esp32 thiab tom qab ntawd xa qhov txiaj ntsig mus rau yam khoom.ai IoT huab platform.

Kauj ruam 1: QHOV TSEEB

Kho vajtse Cheebtsam:

1. esp32 pawg thawj coj loj

2. Qhov av sensor

3. Jumper Xov

Software:

1. Arduino IDE

2. Thingsio.ai

Kauj ruam 2: Kev sib txuas

Av noo noo Sensor ---------------------- esp32 Board

VCC --------------------------------------- 3V3

GND -------------------------------------- NCO

A0 ---------------------------------------- VP
