Proyek ini adalah Termometer Digital Bluetooth menggunakan mikrokontroler ESP32 yang dapat mengukur suhu dan kelembapan udara secara real-time menggunakan sensor DHT11. Data hasil pengukuran dikirimkan ke perangkat Android atau komputer melalui koneksi Bluetooth, sehingga pengguna bisa memantau suhu dan kelembapan tanpa kabel.<\/p>\n\n\n\n

Cara Kerja:<\/strong><\/p>\n\n\n\n

    \n
  1. Sensor DHT11 membaca suhu dan kelembapan lingkungan sekitar.<\/li>\n\n\n\n
  2. Data dikirim ke ESP32 melalui pin digital.<\/li>\n\n\n\n
  3. ESP32 memproses data dan mengirimkan hasilnya melalui Bluetooth Serial.<\/li>\n\n\n\n
  4. Pengguna dapat menerima data tersebut menggunakan aplikasi seperti Serial Bluetooth Terminal (Android) dan Tera Term \/ PuTTY (PC dengan Bluetooth)<\/li>\n\n\n\n
  5. Pembacaan dan pengiriman data dilakukan setiap 2 detik secara otomatis.<\/li>\n<\/ol>\n\n\n\n
