Abstract:
Exhaust fan plays an important role for the kitchen, this is because the kitchen smoke has a
risk to health, especially on breathing. The target of controlling the fan speed automatically
is to get a stable air condition in the kitchen so it will get a more comfortable and safe
conditions for the health of its users. The exhaust fan control speed is with detection of the
smoke levels generated by the cooking process and room temperature, so we can control
speed of the exhaust fan automatically. The control of the exhaust fan speed is based on the
fuzzy logic method. Consisting of two parameters that become input from fuzzy is that
smoke gas of cooking process and room temperature. The results of the tests that have been
done, obtained the success rate of temperature sensors reading 98.5% and the value of gas
consentration is obtained by the rasio between Ro (resistance value of normal condition) and
Rs(resistance value ofsmoke detected). The speed of exhaust fan can be controlled by giving
different volftage.
