Yana bir Arduino ob-havo stantsiyasi (ESP-01 va BMP280, DHT11 va OneWire): 4 qadam

Bu erda siz ESP-01-ning juda kam pinlari bilan OneWire-dan foydalanishning bitta iteratsiyasini topishingiz mumkin. Ushbu yo'riqnomada yaratilgan qurilma siz tanlagan Wifi tarmog'iga ulanadi (hisobga olish ma'lumotlari bo'lishi kerak …) BMP280 va DHT11 va to'plangan ma'lumotlarni ThingSpeak kanaliga yuboradi, men sizning eskizingizni ESP-01ga qanday yuklashni bilasiz deb o'ylayman, shuning uchun men bu tafsilotlarga kirmayman. Maksimal 3,3V DC bilan. Ko'p matn qo'shilmaganligi sababli, darslik shu nuqtadan boshlab tushunarli bo'lishi kerak.

1 -qadam: 1 -qadam: BOM

Uskuna:

1 x Wi-Fi moduli: ESP-01 (men 1024 KB versiyasini ishlataman)

1 x Bosim va harorat sensori: BMP280

1 x Namlik va harorat sensori: DHT11

1 x AMS1117 kuchlanish regulyatori (to'g'ridan -to'g'ri quvvatlantirish uchun ixtiyoriy, yoki siz kirish voltajingizni sobit 3.3Vgacha boshqaradigan boshqa har qanday qurilmadan foydalanishingiz mumkin)
