Program očitava temperaturu i vlažnost zraka u prostoriji pomoću senzora DHT11. Očitane vrijednosti ispisuje na računalu u programu Tera Term. Za vlažnost zraka manju od 60% svijetli zelena LED, a za vlažnost zraka veću od 60% pali se crvena LED. Pritiskom na tipkalo prekida se rad programa na 5sekundi. Odbrojavanje se prikazuje na 7-segmentnom displey-u. Za to vrijeme ugašene su sve LED. Nakon isteka 5 sekundi program nastavlja sa radom tamo di je prethodno stao. Žuta LED predstavlja ticker i blinka svake 0,2 sekunde i time pokazuje da se program izvršava.
