SM03B WIRELESS SMOKE DETECTOR
This product is a photoelectric smoke detector (hereinafter referred to as the detector) that detects smoke using a pair of infrared diodes. Its detection principle is based on the ability of smoke particles to reflect infrared lightThe infrared diodes are arranged inside a special optical chamber. This chamber blocks external light, while allowing smoke to enter. When no smoke is present, the diode receives only a very weak infrared signal. When smoke enters the sensor chamber, the infrared light is reflected and detected by the receiver, thereby activating the alarm.
