AUTOMATIC KITCHEN FAN

Abstract

Cooking is one of the main sources of indoor air pollutants, and may even exceed the contribution from external sources. Cooking can be a tiring experience if thekitchen is not properly ventilated. Despite good ventilation sometimes we need an exhaust fan to moderate the temperature in the kitchen during cooking. But when we are too busy cooking, we often forget the fan and end up cooking without it. A simple solution to this problem is to use a circuit to automate the exhaust fan in the kitchen to automatically turn on when cooking starts. This automatic exhaust fan circuit uses a temperature sensor to monitor the atmospheric temperature and turn on or OFF the fan based on temperature. The results of the study prove that there are advantages by this fan system .
