Smart fan using room temperature sensor and human movement

Fans are electrical equipment that people often need in their daily lives. available the market generally use a manual button to turn it on and off. It is necessary develop system so fan can be turned automatically without press fan. The designed this study has PIR, LM35 Ultrasonic sensor devices, while control uses an Arduino Uno microcontroller. PIR testing done by measuring output for each input object movement. was tested comparing temperature measurement results obtained with using standardized digital thermometer. ultrasonic detected distance reading actual ruler placed under sensor. Overall observing rotation given parameters. criteria used if there human movement room above 28 0C less than 16 cm, then 1 2 rotate simultaneously. Another criterion, below 0C, turns off even though remains because limited cm. showed had worked well, namely behaved according specified criteria. This expected assist humans operating based temperature, movement, distance.
