Development of Intelligent Temperature Controller for Cultivating Box with Constant Temperature

It is very important significance to protecting enviroment and natural resources that change the disused refrigerator into cultivating box with constant temperature . This paper introduces a method to turn the disused refrigerator into cultivating box with constant temperature. The main focus of the paper is the temperature controlling meter based on single chip microcomputer. The basic circuit diagram about the meter was show, and its principle and feature of circuit were described in detail. The cultivating box with constant temperature has a high automatization, a high testing precision and a good reliability. Characteristic test of temperature controller proved that cultivating box with constant temperature has a better characteristic.
