Abstract

Along with the continuous development of science and technology progress and people's requirement for household life gradually become tall, intelligent household has gained the recognition of people, now a complete set of intelligent household equipment is expensive, the average family is difficult to afford the high prices, aiming at this phenomenon, a stable overall function, but low-cost intelligent household products can help people find a way out between price and functionality. This intelligent household USES STM32 processor, mature technology, application transplant convenience, low prices. This household equipment design including hardware design and software design of two parts: hardware design includes: 12864 LCD, reactive temperature, humidity sensor circuit, the concentration of the smoke collecting circuit, ADC conversion circuit, alarm circuit, power circuit, acquisition circuit and lighting lighting control circuit, software design includes the main program, data (temperature, humidity, gas concentration, light) detection and processing, and calibration standard gases, ADC data conversion, when gas concentration overrun alarm program. By the experimental test results show that the smart home devices have automatic detection family environment index and can be conducted to collect information to err on the side of the processed on time, high precision, detection range, good stability, display is simple, easy operation, strong anti-interference ability and other excellent properties.

Key words: ARMv7-M; ADC; Data acquisition and processing; serial communication
