With the development of micro electronic technology and embedded system in China, the current industry is relatively more traditional carbon dioxide and temperature and humidity detection system can not meet the needs of customers. In order to improve the traditional carbon dioxide and temperature and humidity detection system in the control of the short board problem, in this graduation project, will use relatively advanced, fast, intelligent control mechanism. The control brain of the system is the core controller of the 51 series embedded development system, which mainly uses digital control technology to convert the input continuous analog voltage signal into discrete digital signal and transmit it to the LCD. The carbon dioxide and temperature and humidity detection system design has intelligent control, digital display and other functions, and cost-effective, accurate, low energy consumption, simple production, convenient and fast weighing characteristics, has brought a great impact on peoples lives, is very popular in the market.
Carbon dioxide and temperature and humidity detection and control methods are many. This system uses STC89C52RC single chip microcomputer and single chip microcomputer minimum system, carbon dioxide concentration detection sensor MH-Z14A, temperature and humidity sensor, 1602 LIQUID crystal display and other components, design a single chip based on carbon dioxide and temperature and humidity detection system design. The intelligent control system design mainly from the domestic and foreign development, the choice of hardware control components, according to the control principle to draw the hardware circuit, control system software program design and development, software and hardware joint adjustment simulation four aspects in detail. The control system uses AT89C52 embedded development system, sensor signal acquisition circuit, circuit display part, data conversion circuit, reset circuit and clock circuit to form an intelligent carbon dioxide and temperature and humidity detection system.
The intelligent control system design mainly from the domestic and foreign development, the choice of hardware control components, according to the control principle to draw the hardware circuit, control system software program design and development, etc. The control system uses STC89C52RC embedded development system, circuit display part, alarm circuit and other components of intelligent carbon dioxide and temperature and humidity detection system control system.
