STM32-based three-wavelength smoke detection

The current stage of research on the integration of optical fire and smoke detection sensor technology, the current basic focus on red and blue dual-wavelength fire and smoke sensors and the rest of the fire detection information integration technology, specifically for the three-wavelength optical circuit simulation design and integration of the research is less; for the multi-wavelength optical black and white smoke detection balanced technology design of the research is also very little. In view of the above problems, this paper designs a three-wavelength smoke detector based on STM32 microcontroller on the basis of ADPD188BI sensor. This thesis uses embedded technology, based on the ADPD188BI dual-wavelength integrated optical module sensor, in order to carry out technical combing of hardware and software design focus, complete the circuit integration design, to achieve the sensor hardware and software integration design, and in accordance with the national standards GB 4715-2005 "point-type smoke-sensing fire detector", GB20517-2006 "standalone smoke-sensing fire detection Alarm" and other standards independently developed, designed and manufactured test smoke box to carry out compliance with the national standard GB 4715-2005 "point-type smoke detector" performance test verification.
