【花雕动手做】ASRPRO语音识别（20）---彩屏显示DHT11温湿度
本例实验采用DHT11是一款含有已校准数字信号输出的温湿度复合传感器。它应用专用的数字模块采集技术和温湿度传感技术，确保产品具有极高的可靠性与卓越的长期稳定性。传感器包括一个电阻式感湿元件和一个NTC测温元件，并与一个高性能8位单片机相连接。因此该产品具有品质卓越、超快响应、抗干扰能力强、性价比极高等优点。每个DHT11传感器都在极为精确的湿度校验室中进行校准。校准系数以程序的形式储存在OTP内存中，传感器内部在检测信号的处理过程中要调用这些校准系数。单线制串行接口，使系统集成变得简易快捷。超小的体积、极低的功耗，信号传输距离可达20米以上，使其成为各类应用甚至最为苛刻的应用场合的最佳选则。产品为4针单排引脚封装。连接方便，特殊封装形式可根据用户需求而提供。
电原理图
本例实验采用板载三位独立按键，可以搭配实现各种相关的功能。
本例实验的SPI彩色液晶1.77寸显示屏（ST7735驱动）
