Optical Smoke Detector

The Discovery optical smoke detector uses an IR LED which pulses light across a smoke chamber with a photo-diode set an obtuse angle. In clear air it receives no light, but when smoke enters the chamber, light from the LED is scattered onto the photo-diode. A signal is then processed to provide an analogue value for transmission when the detector is polled.
