NB-IoT smoke alarm with life detection function

An NB-IoT smoke alarm with a life detection function comprises an alarm system arranged in the alarm, and functional modules of the alarm system comprise an MCU main control system, a human body induction detection unit, a millimeter wave radar antenna, a smoke detection unit, an NB-IoT communication unit, an NB-IoT antenna, an LED indication driving unit, a buzzer driving unit and a battery powersupply system. The technical key points are that a millimeter wave radar detection technology is introduced, the used millimeter waves are different from light waves and have very strong penetratingpower to smoke, detection and recognition can be rapidly and effectively carried out on a human body through reflection of a radar antenna, and the defects of an existing alarm product in the aspect of a vital sign recognition function are overcome; and an NB-IoT narrow-band Internet-of-Things technology is applied, data collected by the alarm is uploaded to a server in a wireless mode, a lithium-manganese battery is adopt
