Abstract (en)
A smoke detector uses a detector assembly in the form of a sensor and light source. This can be formed as a packaged circuit and can therefore be low cost and have a small volume. The detector assembly is mounted in a housing including a reflector, which redirects the light source light back towards the detector assembly. The sensor receives a changing signal in the presence of smoke resulting from light scattering.
