ProjectsforSchool Fire Alarm Working Model - DIY kit for Science Project  (Multicolor)

At Projects for School, we try to design and develop DIY Working Science Models which can interlink concepts and teach students about multiple concepts together. Fire alarm as a DIY Physics Experiment on electric circuit for a workshop is one of such examples. \n\nA fire alarm actually is a combination of multiple devices that detect fire, smoke or other emergencies through audio / visual sensors and then warn people. The alarms can be of various types and are usually activated from detectors.\n\nSimple and easy to make, this is one of the few important Physics projects for class 10th and 11th that demonstrates the use of IR sensors. The IR sensors work on Infra Red rays and detect heat / light from the nearby environment and change the state of the circuit from non-conducting to conducting upon detection.
