Telah dilakukan perancangan sistem monitoring suhu pada proses pendingin larutan nutrisi hidroponik menggunakan elemen peltier dan TDS meter. Proses pendingin larutan nutrisi hidroponik menggunakan elemen peltier yang terhubung dengan sensor DS18B20 sedangkan TDS meter menggunakan nutrisi ABmix untuk menghasilkan konsentrasi terlarut sebesar 200 ppm – 1100 ppm. Elemen peltier aktif ketika suhu diatas 26°C sedangkan suhu dibawah 26°C elemen peltier mati. Konsentrasi terlarut yang dirancang dapat mengaktifkan buzzer ketika dibawah 200 ppm sedangkan diatas 200 ppm buzzer mati. Data berupa suhu dan konsentrasi terlarut yang didapat kemudian diproses oleh mikrokonteler Arduino Uno kemudian suhu dan konsentrasi terlarut ditampilkan ke LCD. Persentase error yang didapat pada pengujian sensor DS18B20 dengan alat pembanding sebesar 2,08% dan sensor TDS meter dengan alat pembanding sebesar 0,25%.References
