Abstract
Wireless network has been widely used in various environmental monitoring occasions by virtue of its wide distribution range, strong flexibility and convenient layout, which realizes the timely acquisition of simple data. Based on single chip microcomputer and sensor technology, this paper realizes the acquisition, processing and wireless transmission of multiple environmental parameter signals, which provides a new hardware realization method for the combination of environmental parameter monitoring and wireless network.In this paper, environmental parameters as the research object, the use of single-chip microcomputer technology to design it, divided into software design and hardware design, hardware design: STM32 single chip microcomputer is used as the main control chip, DHT11 is used to detect temperature and humidity in the environment, GP2Y10 is used to detect dust concentration in the environment, MQ-5 is used to detect combustible gas value, MS1100 is used to detect formaldehyde value, and OLED display is used to display relevant data. The NB module is used to transmit the detected data to the user’s mobile phone, and the user can set the parameter value by pressing the button, or set the related threshold through the mobile phone. Software design: Keil5 is used as the programming software of this design program, AD is used as the drawing software of this design schematic and PCB, stc-isp is used as the burning software of this design program, and Visio is used as the flowchart drawing software of this design. Through the design of hardware and software cooperation, the relevant parameters in the natural environment can be monitored and controlled, so that the environment is in a good state.
Key words: environmental control; Temperature and humidity; Sensor; Keil5; Single chip microcomputer.
