photoelectric sensor measures the concentration of smoke through a beam of light and a light sensor. When the device is designed, the light beam is deviated from the sensor. When smoke enters the sensing chamber, smoke particles will scatter some of the light beam onto the sensor. As the concentration of smoke gradually increases, more beams will be scattered onto the sensor. When the beam reaching the sensor reaches a certain level, the speaker will ring.
