Fire Alarm Using Logic Gates | Digital Electronics Experiment | Class 12 Physics

In this video on Physics Concepts, we demonstrate a Class 12 Physics practical experiment to make a fire alarm using logic gates. This project helps students understand the real-life application of digital electronics. A fire alarm circuit can be designed using logic gates (such as NAND, OR, or AND gates) along with a temperature sensor or thermistor. When the temperature rises due to fire, the circuit is triggered and activates a buzzer or alarm, indicating danger. 📚 Topics Covered in This Video • Introduction to Logic Gates • Working Principle of Fire Alarm • Use of NAND / OR / AND Gates • Circuit Diagram Explanation • Components Required (ICs, buzzer, thermistor, battery) • Step-by-Step Working • Applications of Fire Alarm Systems This experiment is very important for Class 12 Physics students, FSC practical exams, and electronics projects. It helps in understanding how logic circuits are used in safety systems.
