    Abstract: The parameters such as temperature, humidity and gas particle concentration are essential for the identification of environmental quality. This design used DHT11 temperature and humidity sensor to detect ambient temperature and humidity, CP-15-A4 sensor to detect atmospheric particle concentration, and liquid crystal display (LCD) to display the value of detection. This design used ultra low power MSP430 chip microcontroller to make full use of the abundant logic judgment and numerical calculation and high-grade MSP430 chip register function. Based on the characteristics of the sensor, aiming at the application of microcontroller existing theory, this paper introduces the methods of solving a variety of problems in the concrete design and the experiments verify the correctness of the proposed method.
    Key words: microcontroller; logical judgment; parameters changing; environmental monitoring
