Motion Detector Siv Thingsai.io Iot Cloud 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 txav mus los los ntawm kev siv lub PIR sensor thiab Esp32 nrog rau IOT huab platform Thingai.io

Kauj Ruam 1: Cheeb Tsam

HARDWARE COMPONENTS;

1.esp32 Pawg Thawj Coj Loj Hlob

2. PIR Sensor

3. Jumper Wires

SOFTWARE:

1. Arduino IDE

2. Accountai.io tus account

Kauj ruam 2: Kev sib txuas

Cov kev sib txuas yog ntsiag to yooj yim.

PIR PINS ------------ ESP32 PINS

VCC ------------------- 3V3 ntawm esp32

GND ------------------ GND ntawm esp32

OUT ------------------- D22 ntawm esp32

Kauj ruam 3: CODING

Muab cov cai no tso rau hauv koj li Arduino IDE nrog qee qhov kev hloov kho tshiab, koj lub Motion sensor yuav muab cov txiaj ntsig tau zoo.

Kauj Ruam 4: NTUJ

Nov yog kab ntawv kab lus sawv cev ntawm qhov muaj txiaj ntsig nyeem los ntawm lub ntsuas pa hauv yam khoom, io huab platform,

Kauj ruam 5: Teeb duab

Qhov no yog cov duab sawv cev ntawm qhov muaj txiaj ntsig los ntawm lub sensor. Los ntawm daim duab saum toj no peb tuaj yeem tshuaj xyuas daim ntawv thov ntawm lub ntsuas. Ua Tsaug
