INTRO:

1 Ushbu loyihada men ma'lumotlarni ko'rsatish, SD -karta va IOT -da ma'lumotlarni zaxiralash bilan zarracha detektorini qanday qurishni ko'rsataman. Vizual ravishda neopikselli halqali displey havo sifatini ko'rsatadi.

2 Havo sifati bugungi kunda tobora muhim ahamiyat kasb etmoqda. chang tezligini o'lchaydigan tizimlar bor, lekin ular juda qimmat. Ba'zi tadqiqotlar ko'rsatganidek, bozorda arzon va yuqori sifatli zarracha detektorlari mavjud.

masalan:

www.atmos-meas-tech.net/11/4823/2018/amt-1…

3 Shuning uchun men zarrachalar sonini o'lchov sinflari bo'yicha o'lchashga qodir bo'lgan qurilmani (0,5 mkm dan 10 mkm gacha), natijani oddiy ko'rsatish (neo pikselli halqa), TFT ekranida va SD-kartadagi vaqt muhri bilan zaxiralash.

4 Bundan tashqari, men bluetooth aloqa modulini qo'shdim, u android ilovasi bilan aloqa o'rnatishi va natijalarni IOT serverida e'lon qilishi mumkin.

5 Umumiy qiymati 60 € dan oshmaydi
