Abstract

With the development of modern technology, the production of modern life

continues to improve, for greenhouse technology to cultivate crops can significantly

increase the yield of crops, reducing the agricultural production of the natural

environment and climate change request. However, the greenhouse temperature and

humidity requirements for a series of air composition indicators are very strict, and

greenhouse modernization must have a set of temperature and humidity measurement

and control system, the design is for people living with and the continuous

improvement of production level, to the living environment and the requirements of

the production environment is particularly important, control temperature and

humidity is a typical example, therefore, emerge as the times require an intelligent

temperature and humidity detection system in modern life and fast, convenient and

reliable detection system, especially in the industrial production if the detection of

inaccurate will occur in many production accidents. To provide a better life for

modern people to work, scientific research, and more convenient facilities, we must

start from the SCM technology, all toward digital control system, intelligent control

direction. The design is based on single-chip microcomputer as the core, with the

temperature and humidity sensor, detecting system and related peripheral circuit, can

receive the measurement of environmental temperature and humidity signal, detecting

personnel can be displayed by the LCD data, the temperature and humidity of

real-time monitoring of the environment. The measurement operation all can be

realized through the host computer control software, the measurement signals are

temperature and humidity sensor, the circuit is converted to electrical signals, and

then the data were processed by conversion to SCM, through the software analysis

processing evacuation display device.

The system hardware and software design, including the system of high reliability,

simple structure, realizes the automatic control of temperature and humidity. The

system also applies RS232 and host machine is connected, can parameters related to

the automatic recording of temperature, humidity settings, can also be set at a certain

time automatic recording, available in the meteorological observation.
