Silk was one of economic goods that provided high revenue for agriculturists. Due to changing weather however there were some problems and limitations of silkworm breeding. For instance too hot and humid weather caused mold infection and made the silkworm easily get infected. On the other hand too less humidity might lead to dry mulberry leaves. In addition the agriculturists had no records of the silkworm breeding. This research realized these current obstacles and aimed to develop an embedded Android application system to control electrical system and temperature in a silkworm house. The operation was divided into 3 parts consisting of direct control via control board of the silkworm house control via wireless Bluetooth on the application SMS delivery system to warn distant users. The results of this study provided the electrical control system and temperature in the imitated silkworm house. It could automatically control the internal temperature and retrieve data of control equipments via the Android application system and Bluetooth for near distance about 20 meters and far distance by sending SMS. The system also measured the actual temperature and humidity from SHT11 Module. The temperature could be fixed between 24-30 Celsius while the humidity could be defined between 60-90% by applying ventilators lights and jet sprayer
