Abstract
As people's lives and the continuous improvement of production level of
the living environment and production environment is particularly important on
the obvious, temperature and humidity control is a typical example, it is
temperature and humidity detection system came into being the life of modern
production A smart, efficient, convenient and reliable detection systems,
especially in the industrial production is not accurate if the detection of the
production occurs in many accidents. Chemical production, such as the detection
of temperature can lead to inappropriate production efficiency and product
quality to reduce the decline. And now used in temperature and humidity
detection system is usually an accuracy of 1 ℃ or 0.1 ℃ mercury, kerosene or
alcohol thermometer the temperature detection and physical simulation using
traditional methods of quantitative detection of humidity. These temperature and
humidity testing of calibration intervals are usually very dense, it is not easy to
distinguish accurately, reading difficulties, and their relatively large heat capacity
to heat balance the time required is longer, it is difficult to read accurate, and very
inconvenient to use.
Work for the modern, scientific research, to provide a better life more
convenient for the facilities will need to start from the single-chip technology, all
toward the digital control, intelligent control of direction. The design is based on
single-chip microputer as the core, with the temperature sensor (DS18B20) and
humidity sensor (HIH-3610), and related peripheral circuits of the detection
system ponents, you can receive the measured temperature and humidity
environment signal detection can through the digital data display, real-time
monitoring of temperature and humidity environment situation. Operation of all
the measurements are available through the host control software to achieve,
temperature and humidity sensors measuring signal is converted to electrical
