2025 Muallif: John Day | [email protected]. Oxirgi o'zgartirilgan: 2025-01-23 15:14

HEY ….. bugun biz ESP32 yordamida yorug'lik intensivligini o'lchash va qiymatlarni THINGSAI IOT bulutli platformasiga joylashtirish haqida bilib olamiz.

Ushbu loyihani amalga oshirish uchun talablar

1. ESP32 ishlab chiqish kengashi (men ESP32 DEVKIT V1 dan foydalanganman)

2. LDR sensori

3. Jumper simlari

4. THINGSAI IOT PLATFORM -dagi hisob

1 -qadam: THINGSIO platformasini yaratish va unga kirish

THINGS AI hisobiga kiring. Agar siz yangi bo'lsangiz, ro'yxatdan o'tish tugmachasini bosib, ro'yxatdan o'ting va barcha hisob ma'lumotlarini to'ldiring. Hisob qaydnomangiz yaratiladi va shu vaqtdan boshlab siz bulutli platformada ishlashingiz va o'zingizning shaxsiy loyihangizni yaratishingiz mumkin bo'ladi

2 -qadam: Yangi loyiha yaratish

Hisobga kirgandan so'ng, loyihani yaratish uchun yangi loyihani bosing va keyin loyiha nomini bering.

3 -qadam: Yangi qurilmani yaratish

Loyihani yaratgandan so'ng, siz yangi qurilmani yaratishingiz kerak. Qurilmaning nomini bering va qurilma identifikatorini qo'lda yoki tizim orqali kiriting.

4 -qadam: qurilma parametrlarini aniqlash

Qurilma parametrini bering va keyin parametr turini tanlang

5 -qadam: Qurilmani yangilash

Parametrni tanlang va keyin qurilmani yangilang

6 -qadam: kodlash

Namunaviy kodlardan esp32 kodini tanlang, uni nusxa ko'chiring va keyin arduino IDE -ga joylashtiring va talabga muvofiq kerakli o'zgartirishlarni kiriting. Men kodni quyida berdim

7 -qadam: Kengash va portni tanlash

Asboblardan taxtani tanlang, so'ngra com portini tanlang

8 -qadam: O'chirish ulanishlari

Kodlash amalga oshiriladi, keyin quyida aytib o'tilganidek, quyidagi ulanishlarni amalga oshiring

Ulanishlar:

Esp32 GND - LDR sensori GND

LDR VC uchun 3V3 0f esp32

LDR A0 ga esp32 VP

9 -qadam: kompilyatsiya va yuklash

kodni esp32 ga to'plang va yuklang, so'ngra ketma -ket monitordan o'qishni o'qing. Bu shunday natijani ko'rsatadi

10 -qadam: ketma -ket monitor

Qiymatlar ketma -ket monitorda olinadi va keyin THINGSAI IOT Cloud platformasiga yuboriladi.

11 -qadam: o'qishlar

Bu esp32 kartasidan olingan qiymatlarni ko'rsatadi.

12 -qadam: Grafik tasvir

Bu olingan qiymatlarning grafik tasviri. Darslik shu bilan tugadi. Tushundingiz deb umid qilaman. Rahmat
