ARDUINO Monitoring 5 SUHU Thermocouple Tipe K DATALOGGER EEPROM (Multiple Sensor)

ARDUINO Monitoring 5 SUHU Thermocouple Tipe K DATALOGGER EEPROM (Multiple Sensor)


           Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang berfungsi untuk memonitor suhu menggunakan sensor thermocouple sebanyak 5 buah dan dimonitoring secara bersamaan. alat ini menggunakan sistem penyimpanan EEPROM sebagai dataloggernya dan juga terdapat tombol konversi yang dapat merubah dari celsius ke reamur ataupun ke kelvin atau fahrenheit. untuk lebih jelasnya berikut adalah komponen dan programnya,



a. Arduino Uno




b. Sensor Thermocouple Tipe K (5 pcs)




c. LCD + I2C






d. Program Arduino IDE

e. Cara Menjalankan Alat

       Cara menjalankan alat ini yang pertama yaitu hubungkan alat dengan power supply atau adaptor kemudian pastikan semua komponen sudah terpasang secara tepat, untuk pin arduino yang terhubung ke sensor bisa dilihat pada program di bagian atas. selanjutnya tekan tombol untuk konversi, simpan data ke EEPROM dan baca data yang ada di EEPROM.
