Esp32 va Thingsio.ai platformasi yordamida haroratni o'lchash: 6 qadam

2024 Muallif: John Day | [email protected]. Oxirgi o'zgartirilgan: 2024-01-30 13:26

Ushbu qo'llanmada men esp32 ishlab chiqarish kartasida mavjud bo'lgan ichki harorat sensori yordamida atrofdagi haroratni o'lchash haqida tushuntiraman. esp32 yaqinlik sensori, sensorli sensor, harorat sensori sifatida ishlatiladigan zal sensori kabi ko'plab ichki sensorlarga ega. Ushbu qo'llanmada biz harorat sensori haqida gaplashamiz.

Dasturiy ta'minot:

1. Arduino IDE

2. Thingsio.ai

2 -qadam: Esp32 -ni blokirovka qilish
