Smoke detector design example
Description
This Smoke Detector design example is based on the NXP P89LPC9107.
If we can reliably monitor the smoke density for a working site, we can prevent and minimize the damage of fire accidents and thus reduce the cost of property damage and loss of human life.
The most commonly used detectors are the ionization detectors and the photoelectric detectors.
Ionization detectors are prone to malfunction when used in noisy, dusty, or damp environments and are subject to frequent maintenance.
Ionization detectors also produce radiation pollution.
Therefore, the popularity of ionization detectors has been on decline while photoelectric detectors are increasing in popularity.
Photoelectric detectors detect the intensity of ultraviolet light pulses that are reflected from the smoke in order to deduce the density of the smoke accordingly.
