With high sensitive sensor, this smoke sensor can be applied in many places.

The detector adopts the refection principle of smoke particles that can reflect infrared light. The main circuit includes a MCU processing section, an infrared-emitting portion and an infrared receiving portion. Transmitting and receiving diodes are placed in the optical chamber which can shield stray light from outside interference, but does not affect the smoke getting into the detector. Usually when in a smoke-free environment, infrared signal is very weak. When smoke enters the optical chamber,due to scattering effect, the infrared signal increases. When the smoke concentration accumulated reaches to the MCU alarm level, the detector will flash warning lights and warning alarm, meanwhile sending alarm signal to trigger other devices which connected to it.
