一.温湿度原理
1.1 时序图
(1).下图一是DHT11总的时序图。
(2).图二对应图一的左边黑色部分，图三对应图一的绿色部分，图四的左部分图对应图一的红色部分，图四的右部分对应图一的黄色部分。
(3).首先图二部分是单片机向DHT11发送我要开始的信号，此时单片机IO口处于输出模式，输出低电平至少18MS，之后释放主机总线(高电平)，时间是为图五的第二行，之后把单片机IO口设置为输入模式，在图三中，83us拉低和87us拉高是DHT11对单片机的响应时间，也就是回应它我收到了，这时候可以用whille循环卡着，之后87us的高电平过去以后，变成了在图三开始发送数据位置(低电平)，也就是图四的54us的位置，54us是准备发送数据，54us一旦过去就变成了高电平，高电平持续时间的多少决定了DHT11发送给单片机的数据0还是1，23us-27us是数据0，68us-74us是数据1，那么我们可以延时30us,如果30us过后还是高电平就是数据1，如果变成了低电平就是数据0，这里要注意，延时30us后，如果是数据1，数据1延时时间还未到，所以可以用while循环卡着它的时间过去，具体看下面代码。
