Yaqinlik o'lchami: 5 qadam

2024 Muallif: John Day | [email protected]. Oxirgi o'zgartirilgan: 2024-01-30 13:25

Ushbu qo'llanmada men qurilmaning yaqinligini o'lchash va qiymatlarni Thingsai, io bulutli platformasida zal sensori va esp32 ishlab chiqish paneli yordamida e'lon qilish haqida tushuntiraman.

Hall effekti sensori - bu magnit maydonining kattaligini o'lchash uchun mo'ljallangan qurilma. Uning chiqish kuchlanishi magnit maydon kuchiga to'g'ridan to'g'ri proportsionaldir. Zal effektli sensorlar yaqinlikni aniqlash, joylashishni aniqlash, tezlikni aniqlash va joriy sezish uchun ishlatiladi.

4 -qadam: Natija:

Sensordan o'qiladigan qiymatlar IOT bulutiga muvaffaqiyatli yuborilmoqda va grafik vaqtga yaqinlik sifatida yaratilmoqda. Bu bilan sensorning ishi tahlil qilinadi va kerakli dastur sohalariga muvofiq ishlatiladi.
