Functions

The optical sensor in the smoke detector uses the scattered-light method. An LED transmits light to the measuring chamber, where it is absorbed by the labyrinth structure. In the event of a fire, smoke enters the measuring chamber and the smoke particles scatter the light from the LED. The amount of light hitting the photo diode is converted into a proportional electrical signal. The entire electronic system is protected inside the detector. The base is only used for the detector contact.
