WebIt detects the light coming, which tells the system that the circuit is complete. However, when smoke enters inside, the smoke obstructs the light. The redirected light falls into the photocell, which is present inside the chamber. When this photocell detects light, it rings the alarm. Here's a diagram of how a photoelectric smoke alarm works. WebWhen smoke molecules enter the ionization chamber, the smoke particles attach to the ions and neutralize them. Consequently, the total number of ionized particles in the chamber is reduced. This reduction yields a decrease in the chamber current that is sensed by the electronic circuitry. The drop of current between the plates triggers an alarm.
