Abstract
Are mainly introduced in this paper based on single-chip puter temperature and humidity meter design, through the LCD display measured by the temperature and humidity. System adopts sets and humidity sensor and A/D converter for the integration of SHT11 chip microcontroller processing, through that explained temperature and humidity data collection and transmission project, LCD display, humidifying functions and achieve these functions and design of hardware circuit and the software programming. This paper also presents the hardware circuit principle diagram, the main program and the terrorists program flowcharts, through the software and hardware design makes duckshot almost temperature and humidity plan has intelligence, high accuracy, high reliability, etc advantages, has wide application prospects. This system structure is simple, practical, improve the measurement accuracy and efficiency
