The Design of Temperature and Humidity Control
Instrument which is based on MCU

Abstract: The design and implementation of measurement and control temperature
and humidity is MCU system, through which the temperature and humidity
measurement LCD. System adopts set temperature and humidity sensor and A/D
converter for SHT11 chip microcontroller processing, through that other modules
including real-time clock/date produce circuit and the off-gauge alarm circuit, the
value of measurement for real-time display and alarm. The paper introduces the
pany based on AT89C51 single-chip series of temperature and humidity
measurement and control system and real-time display system design, including the
hardware structure and principle, and the corresponding software design, including
the design of the software and its key process and procedure. System structure is
simple, practical, and improve the measuring precision and efficiency.


Key words: MCU, SHT11, LCD, DS1302, temperature and humidity control
