This Circuit Can FEEL Heat! 🤯 | Simple Temperature Sensor Circuit (No IC!)

#TemperatureSensor #Thermistor #ElectronicsProject Have you ever wondered how electronics can sense temperature just like human skin? 🤯

In this video, I show you how to build a simple yet powerful temperature sensor circuit using a BC547 NPN transistor, 10K thermistor, and resistor — no microcontroller, no IC, no coding required!

This beginner-friendly project runs on DC power and can control:

💡 LED indicator

🔔 Buzzer alarm

🌬️ Fan

⚡ Relay (optional upgrade)

You’ll learn:
✔ How a thermistor detects temperature
✔ How a BC547 transistor works as a switch
✔ How heat turns devices ON automatically
✔ Real-life applications of temperature sensors

This circuit is perfect for:

Students & beginners

Electronics hobbyists

School & college projects

Understanding analog electronics

📍 Applications include:

Over-temperature protection

Fan control circuits

Heat alarms

Battery safety systems

Smart electronics projects

⚠️ Note: Temperature behavior changes with environment, so resistor values may need adjustment depending on room temperature.
