//Challenge Kandang Ayam Potong oleh Hendry Kurniawan 

//Kondisi Kandang Ayam yang ideal berdasarkan data internet:
//Kelembaban sekitar 60 %
//jika kelembaban <= 60% maka pompa air hidup, jika >= 60% pompa air mati
//Suhu sekitar 20 - 25 C
//JIka suhu <= 20 C maka Relay Heater hidup
//JIka suhu >= 25 C maka Relay Blower hidup
//Cahaya sekitar 40 lux
//jika <= 40 lux maka lampu hidup
