摘要:The tem-perature in a room is very inuential in the comfort of thepeople on therein. Because the cost of air conditioning isvery expensive, especially for the cost of electricity, thenmost people here use a fan. Problems on this paper isonly limited to how the temperature can be detected bythe sensor and displayed on the seven segment. As well asthe workings of the tools created. Writing this accordancewith the practices conducted by the author based on man-ufacturing equipment made by the author, the collectionof data from various sources and poured it in this paper.In this tool there LM35 temperature sensor which can de-tect the temperature in a room. Then the temperaturewill be detected compared with the temperature limits onthe program included in microcontroller. When the tem-perature has reached a certain limit then the fan will light/ turning until the temperature dropped. When the tem-perature is still rising, it is up to the limit temperatureparticular, the buzzer will sound. Temperature is detectedwill be displayed on seven segment. From experiments doneshowed that the fan This automatic can have several con-ditions that can cause changes in the seven segment, theoutput of LM35, the output of ADC, state of the fan andbuzzer. If the room temperature has reached a value of 30C then only will cause the fan rotates while the buzzer is notrings. However, when the temperature reaches room tem-perature 32 o C it will caused the fan was spinning and thebuzzer will sound. For accelerate the decline in fan roomtemperature used should be fan large wind. Because if thefan is too small, then the low temperature desired can notbe achieved. The system is only able to reduce tempera-ture from initial temperature 34 o C until the temperature nally reaches 29 o C when used big fan. Small fan (20 W)was only able to lower the temperature of 1 o C, and fanlarge (55 W) that is used is only able to lower the tempera-ture of 2 o C of temperature initially. It takes a bigger fanthe ability to lower the temperature greater. The systemwas to control the temperature within the limits the abilityof the fan that is used.
