Design of Temperature and Humidity Control System of Imitation Natural Biological Growth

The design is a greenhouse simulation of temperature and humidity control system based on DS18B20 digital temperature sensor, which has the characteristics of imitation natural environment, the system can simulate biological growth in the natural environment under the best condition of temperature and humidity in indoor according to the characteristics different biological growth in natural environment. In this paper, first of all, analysis of environment state of the biological growth process to find the best growth laws, and then to control by computer in accordance with the growth laws, external circuit of the intelligent temperature control system is simple, which has the functions of good accuracy, high reliability and with long-range multi-point temperature and humidity measurement and control. According to the analysis in this paper, an artificial natural environment created in a room, and Acanthopanax Senticosus have been cultivated there. By comparing with the artificial Acanthopanax Senticosus' elements, drug effect and natural Acanthopanax Senticosus', there isn't any difference. It not only can be used for more complex control of greenhouse temperature and humidity measurement, but also can be used for temperature and humidity control at the fields of simple carriages, cars and so on.
