Simple Temperature Controlled DC Fan Circuit is like smart fan, which uses special sensor to feel heat around; so when place, it get too hot then circuit makes fan run fast like turning AC high. Therefore, if the place cools again then fan slow down or stop to save power, hence, this circuit uses parts […]
