and automatically on the temperature and humidity for testing, then bined software
programmable, the environmental temperature and humidity parameters of converted to
a decimal number, through a digital display out.And, because after design software
programming, if coupled with appropriate control circuit will realize the environmental
temperature and humidity control systems. Other words, when the environment is
temperature and humidity is low, by the control of the control circuit for increasing of
temperature and humidity of the environment; when the of temperature and humidity
environment is too high, will be interfere by external forces environment, reduce of
environmental temperature and humidity ; achieve the temperature humidity of the
environment a relatively steady state control purpose.
Through the design microcontroller of temperature and humidity detection systems
more to the myth of understanding of microcontroller function and principle. It was only
learning the principles of knowledge, but real life applications do understand too little. By
design, learning a lot own ability is a great improvement.
