Abstract:  The traditional smoke alarm has the problems of high power consumption and cannot be interconnected, so it is difficult to meet the requirements of practical applications. This paper designed a low- power wireless smoke alarm, using a lowpower, low- voltage special integrated circuit RE46C190 for photoelectric smoke detector and an ultra- low- power wireless single-chip CC1310 less than 1 GHz, so that the system standby current is about 14 μA, the theoretical standby life is up to 11 years, and the wireless communication distance reaches 1 km. It satisfactorily meets the requirements of low power consumption and wireless interworking, and provides a new solution for smart fire protection research. 

Key words: smoke alarm, low power consumption, wireless communication
