Abstract

Flower room as a special relatively closed environment, the change of room temperature and illumination is the most significant impact on crops. Aiming at the problem of high cost of the current control system, a new temperature and illumination control system for flower room is presented based on single chip microcomputer. The system obtains current temperature and illumination value depends on the temperature sensor and the photosensitive sensor, and then they will be compared with the setting threshold range. If the measured value is within the range, the original sate will remains unchanged. If outside the range, the control system will be activated to realize the corresponding adjustment, and at the same time the real time information could be displayed on the LCD screen accurately. The result shows the system works stably and it has good application value.
