Web29 de abr. de 2024 · Americium-21 is the radioactive material that passes between the electrodes and transforms the air molecules into positive and negative ions. These charged ions complete a circuit and current flows. As a result, the smoke detector works according to its intended procedure. During a fire, smoke enters the detector. WebDescription. Here is a simple fire alarm circuit based on a Light Dependent Resistor (LDR) and lamp pair for sensing the fire. The alarm works by sensing the smoke produced during fire. The circuit produces an audible alarm when the fire breaks out with smoke. When there is no smoke the light from the bulb will be directly falling on the LDR.
