The invention belongs to the fire alarm detection technology field and provides a redundant smog detector and a system. The redundant smog detector comprises controllers connected with a power source portion, a code receiving portion and a code returning portion, wherein the controllers comprise a first controller and a second controller, the first controller is connected with a first smog sensing portion, and the second controller is connected with a second smog sensing portion; for the system, the redundant smog detector is in hitched with a bus, the bus is connected with a first general controller and a second general controller, the first general controller comprises a first system control portion and a first code transceiving portion, the second general controller comprises a second system control portion and a second code transceiving portion, and the first code transceiving portion and the second code transceiving portion are respectively connected with the bus. According to the redundant smog detector and the system, problems that multiple complex conditions can not be satisfied by a smog detector in the prior art, a damage rate is high, service life is short, error reports constantly occur, detection precision seriously decreases as time goes by, and the system facing various situations can not work normally are solved.

The invention discloses an electronic cigarette capable of detecting blood oxygen saturation, comprising a main body, a partition is fixedly connected to the left end of the inner cavity of the main body, a battery is fixedly connected to the right side of the partition, and the inner cavity of the main body is fixedly connected with a battery. The oil reservoir is fixedly connected to the right end, the atomizer switch and the air flow sensor are fixedly connected to the bottom of the inner cavity of the body and located on the right side of the oil reservoir in sequence from left to right, and the top end of the inner cavity of the main body is fixedly connected There is an atomizer, and the middle end on the right side of the main body is provided with a smoking port. In the present invention, a blood oxygen measuring device is embedded on the left side of the sliding seat, and the blood oxygen saturation in people's body can be detected through the functions of the reserved groove, the push rod and the push handle, the sliding rod and the spring, and the blood oxygen saturation can be detected in the blood. When the oxygen saturation exceeds the highest preset value or is lower than the lowest preset value, the alarm sounds an alarm, which solves the problem that the existing electronic cigarette cannot detect the blood oxygen saturation of the human body, which is not conducive to people's health.
