Fire Alarm Circuit Kit DIY | BC547 Transistor Electronics Project Kit for School Science Fair | Fire Detector Sensor Buzzer Alarm Kit for Students Learning STEM Projects

Build your own DIY Fire Alarm Circuit Kit using BC547 Transistor and learn the basics of electronics, circuit design, and sensor-based automation. This kit is designed for school students, hobbyists, and beginners in electronics. It helps understand how a heat-sensitive fire detection system works using a thermistor and transistor switching.

The kit includes all required components such as BC547 transistor, resistors, capacitors, thermistor, buzzer, wires, and a breadboard or PCB to assemble the circuit easily. Ideal for STEM education, school science fair projects, and electronics workshops. No programming or soldering required, making it perfect for beginners.

This fire alarm project is based on the principle that the resistance of the thermistor changes with temperature, triggering the transistor to activate the buzzer. The compact and reusable kit is also a great way to introduce the fundamentals of sensor-based automation, transistor switching, and alarm circuits.

Whether you're a student, parent, or teacher, this fire alarm circuit kit offers a fun and educational experience. It’s proudly Made in India and comes with after-sales support and free learning resources. Use it to enhance your child’s interest in STEM learning, electronics, and innovation.
