一种湿度检测电路的设计
Design of Humidity Detection Circuit
摘要
Abstract
Humidity is an important environmental factor for industrial and agricultural production and people's daily life, in order to achieve fast and stable high brightness display, the method of combining capacitive humidity sensor and microcontroller was used to design humidity detection circuit. The sensor, microcontroller, A / D conversion, display circuit components and modules based on selection and design are proposed. In the process of detecting, the humidity sensor HM1500 converted the humidity signal into electrical signals, which were sent to ADC0809 and processed by C51, then displayed by MAX7219. Detection circuit has characteristics of clear principle, simple structure, high sensitivity, good stability, high brightness digital display and so on.关键词
