The SM-02 is a photoelectric smoke detector that utilizes infrared diodes to detect smoke particles. When smoke enters the detector's shielded chamber, it reflects infrared light, triggering an alarm once a certain density is reached. Designed with ASIC technology, it features dustproof, anti-moth, and anti-external light interference capabilities.
