| Abstract: | In this article, a multi--dot humidity measuremeng system based on MCU is introduced, using DS2450, humidi- ty sensor and single chip build up sensor networks DS2450, which can detect the multi--dot humidity, gave the hardware circuit and the software. Because of the characterristic of 1--wire circuit, it can convert the analog signals to digital signals derectly and has the ability of measuring distance multi-dot humidity with high accuracy. This system applied in such domains as warehouse detecting humidity, greenhouse control system and supersisory productive process etc |
