Abstract: Apparatus, systems, methods, and related computer program products for handling temperature variation with optoelectronic components of a hazard detection system are described herein. A power characteristic of an optoelectronic component of the hazard detection system may be used to determine a temperature of an environment of the hazard detection system. A power characteristic of an optoelectronic component of the hazard detection system may be used determine a smoke condition of an environment of the hazard detection system. Optoelectronic components of the hazard detection system may be optically coupled to determine a smoke condition of an environment of the hazard detection system. Multiple optoelectronics of the hazard detection system may be operative to detect forward scatter and back scatter of one or more types of light to determine a characteristic of a hazard particle.
