Termostat v11 - Celsius version.inoArduino

// Celsius versi v1.1// Kode program solusi termostat smarthome Arduino yang cerdas, // berdasarkan papan Arduino Nano (atau lebih tinggi), sensor termo DS18B20, Adaptor Bluetooth HC-05, layar OLED bicolor I2C 128X64.// Sistem dapat dikontrol dengan tombol dan smartphone Android melalui bluetooth.//// Ini menangani boiler gas HEATER, ventilator AC kamar mandi, dan PENCAHAYAAN dapur - diputar dengan relai .// Pemanas memiliki dua cara kerja. 1:Mode Satu Kali Pemanasan (15 menit), 2:Mode termostat (prioritas lebih tinggi). Suhu target yang disesuaikan// disimpan di EEPROM. Program mendeteksi kesalahan perangkat keras dan pembukaan jendela - dalam kasus ini pemanas berhenti dan/atau tidak mau menyala.//// Dirancang dan diprogram oleh Gyula Osi.// Hak dilindungi

Thermostat v11 - Fahrenheit version.inoArduino

// Fahrenheit version v1.1// Program code of an intelligent Arduino smarthome thermostat solution, // based on Arduino Nano (or higher) board, DS18B20 thermo sensor, HC-05 Bluetooth adapter, I2C 128X64 bicolor OLED display.// The system can be controlled by buttons and Android smartphone via bluetooth.//// It handles the HEATER gas boiler, the bathroom AIRING ventilator and the kitchen LIGHTING - swithed with relays.// The heater has two working ways. 1:One Time Heating (15 mins) timed mode, 2:Thermostat mode (higher priority).
