湿度传感器在农作物生长环境参数监测仪中的应用研究
摘  要： 本应用主要利用16位单片机SPCE061A作为控制器，电容式湿度传感器HS1101作为测量湿度方案的湿度监测仪的设计。其基本原理是当环境湿度发生改变时，湿敏电容的介电常数发生变化，使其电容量也发生变化，其电容变化量与相对湿度成正比，从而根据电容值计算得到湿度值。该湿度监测仪具有语音播放功能，利用按键控制湿度的测量和湿度值的实时播放。精度准，测量速度快，及其易操作性，可广泛应用于工农业生产、气象、环保等部门，为人们生产生活提供便利。

The Research of Humidity Sensor Application in the Crop Growth Environmental Parameter Monitor
Abstract: This paper introduce a measuring humidity monitoring program design,16-bit single-chip SPCE061A microcomputer as the controller, capacitive humidity sensor HS1101 as measuring humidity program .The basic principle of the design is that the  dielectric constant of the humidity capacitance changes when the humidity in environment changes, while it is also a change in capacitance . the capacitance change is directly proportional to the amount and relative humidity, so the humidity value ia calculated  according  to the value of the capacitance. The humidity monitoring device with voice playback function can  use the keys to control the measure  of the humidity and the value in real-time broadcast. Because of the advantage such as Prospective accuracy, rapid measurement speed, and easy interoperability, can be widely used in industrial and agricultural production, meteorological, and environmental protection sectors, and supply the convenince to people for producting and living.
