摘　　要：湿度是指空气中水汽含量的多少或空气干湿的程度。在果蔬储存,医院呼吸机和室内空调等等都需要考虑湿度。测量湿度的方法有很多种,现在设计一个简单的电路对湿度进行检测估计。考虑现有的测量方法和仪器,本次设计电路更加简单方便,成本也比较低。更适合在一些需要简单估计湿度的环境。Humidity refers to the amount of water vapor in the air or the degree to which the air is dry and wet. Humidity needs to be considered in fruit and vegetable storage, hospital ventilators and indoor air conditioners. There are many ways to measure humidity. Now a simple circuit is designed to detect and estimate the humidity. Considering the existing measurement methods and instruments, the design circuit is more simple and convenient, and the cost is relatively low. It is more suitable for environments where simple estimation of humidity is needed.
