This paper presents a design scheme for a new type of photoelectric smoke detector alarm. First, it briefly introduces the ultra-low power consumption and automatic signal acquisition microcontroller MSP430F2012, and then elaborates on the hardware modules and software design process. By adopting the low power consumption, fast speed and low cost operational amplifier LM358, the hardware and software design meets the low power consumption requirements of the system and realizes the basic functions of the smoke detector alarm, with low power consumption, stable performance and strong practicality. Chinese Keywords: Photoelectric smoke detector alarm; MSP430F2012; low power consumption; operational amplifier Independent smoke detectors are suitable for fire prevention and alarm in civil buildings. According to the working principle, they can be divided into photoelectric principle and ionization principle. Photoelectric smoke detectors are smoke detectors made by using the principle of smoke scattering light beams. Traditional single-point smoke detectors are difficult to meet the mandatory certification requirements of the new national standard GB20517-2006 \"Independent smoke fire detection alarm\" [1] due to the lack of battery monitoring, low voltage smoke alarm and other functions, and are gradually eliminated by the market. The single-point smoke detection alarm proposed in this paper adopts TI\'s MSP430F2012 microcontroller as the main control chip, uses its ADC module to collect smoke and battery voltage changes, and has a self-test function. The design goals strive for reliability, stability, practicality and ultra-low power consumption, in line with the basic requirements of the new national standard.
