Research and Design of Intelligent Greenhouse Temperature Control System for Energy Saving

Temperature is related to various industries. A digital temperature control system is designed in this paper. This system hardware is composed of Freescale micro control unit, DS18B20 temperature sensor, 12864 liquid crystal display, alarm and drive circuit. The program is compiled in Freescale CodeWarrior integrated development environment. Experiment result states clearly that this system can monitor and display environment temperature in real-time and has alarm function. If the temperature is higher or lower than set value, the drive module starts to cool or warm. Some measures to save energy are adopted in this design. It has practical value.
