N2 - This article aims to address the limited sensitivity caused by indoor light source interference and false alarms due to cooking smoke in optoelectronic smoke detection applications. We propose a hybrid modulation optical communication and specific wavelength device-based water mist and smoke discrimination sensing system. The system achieves anti-indoor light source interference at both component and circuit levels, and utilizes a self-developed bandpass optical detector combined with an optical communication hybrid modulation algorithm to further increase the signal-to-noise ratio. Additionally, based on the optical characteristics of smoke, the system uses a multi-wavelength bandpass optical detector array to differentiate between fire smoke and cooking smoke, thereby reducing the system's false alarm rate.
