<![CDATA[In general, conventional cattle sheds using manual systems and human labor are very reliable, in the conventional process of heating cattle sheds, we still encounter many using oil stoves and lamps as a DOC heating process. However, the use of oil stoves and lamps is dangerous and unstable. In addition to the DOC heater using the lamp, there is also a DOC heater using an element heater. The advantage of using a heating element, the temperature can be adjusted according to your needs. The use of heating elements in chicken coops is still rarely used. Therefore, a research was conducted on the manufacture of a temperature and humidity monitoring control system based on Arduino Mega in the Day Old Chicken (doc) cage. DHT 11 sensor accuracy level calibrated with room temperature measuring instrument Taffware HTC-2 is known DHT 11 sensor has an accuracy in reading temperature that is 96% with a dispute of 3.8%. And the accuracy in reading humidity is 89.8% with a difference of 11%.]]>
