How to Build a Temperature-Controlled Fan (Auto On/Off) | Easy DIY Circuit !!
Welcome back to NextGenCircuits! In this video, we are going to build a super simple yet highly efficient Automatic Temperature-Controlled Fan Circuit. This smart DIY project automatically turns ON a 12V DC fan when the temperature rises above a certain limit and turns it OFF when it cools down. Yeh circuit aapke amplifier, power supply, ya kisi bhi custom gadget ko overheat hone se bachane ke liye perfect hai. Best part? Isse banane ke liye hume kisi micro-controller (jaise Arduino) ki zaroorat nahi hai—yeh poora project basic electronic components par chalta hai! Components List: MOSFET: IRFZ44N (1x) Thermistor: 10k NTC Thermistor (1x) Variable Resistor (Potentiometer): 10k (1x) Resistor: 1k Ohm (1x) Heat Sink: Mini Heat Sink (1x) Power Source: 12V DC Supply Output: 12V DC Fan 💡 How It Works (Yeh Kaise Kaam Karta Hai): Is circuit ka dil NTC Thermistor aur IRFZ44N MOSFET hain. Jaise hi temperature badhta hai, thermistor ki resistance kam ho jati hai. Isse MOSFET ke 'Gate' pin par voltage badhta hai. Jab yeh voltage threshold ko cross karta hai, MOSFET switch-on ho jata hai aur fan chalne lagta hai. 10k ka variable resistor aapko yeh set karne ki azaadi deta hai ki fan kis exact temperature par chalna chahiye. Agar aapko yeh project helpful laga ho, toh video ko LIKE zaroor karein, apne tech-friends ke saath SHARE karein, aur NextGenCircuits ko SUBSCRIBE karna na bhoolein! #NextGenCircuits #DIYElectronics #TemperatureController #IRFZ44N #ElectronicProjects #DIYCircuit
