摘要：This re-search is intended to make a smart home concept that isable to respond to changes in weather, especially rain. Thissmart home using 3 sensors that complement each other.The sensor used is a temperature sensor (LM35DT), lightsensor (LDR), and a conductivity sensor which is sensi-tive to water, which all inputs are connected to the mi-crocontroller AT89S51. This concept will be reading theweather conditions around it, using its sensors. Outputfrom these sensors will be input for the microcontrollerAT89S51, which will process the information, obtained inaccordance with the program. The result of processing in-formation by the microcontroller AT89S51 will determinethe inputs, which go into the output of this concept, namelyautomatic roof that is controlled by a motor driver L293D.If the incoming information is information about the con-dition of rain, the roof will be closed automatically, so thatwill secure anything on underneath. This automatic roofwill reopen, if the information captured by the sensors isinformation about the condition of no rain. In the eventof a rainy conditions with a special or unusual case, thenthe concept is provided by conductivity sensors, which aresensitive to water, so the roof will soon be shut down auto-matically if the sensors are exposed to water and will ignorethe information that goes into the 2 pieces of other sensors.The sensor is also used as a last safety of rainy conditions.
