This product named Photoelectric smoke detector detects smoke by a couple of infrared diodes. The principle of detecting is granule in the smoke can reflect infrared light. Infrared diodes are placed in the special chamber. The chamber can shield external light, but don’t affect the smoke into it. If there is no smoke, the diode can receive very weak infrared light. When the smoke entering the detector, the diode receives strong infrared light.
Features:
◆MCU automatic processing technology
◆Manual test
