DHT11器件采用简化的单总线通信。单总线只有一根数据线，主从机之间的数据交换、控制命令等均由单总线完成。在单总线系统中，只有当主机呼叫从机时，从机才能应答。 挂载于单总线上的设备，必须通过一个漏极开路或三态端口连接至该数据线，以允许设备 ...

Every year brings a new hit app that captures everyone's attention. In the wake of Vine (RIP), Snapchat, and other must-use platforms of the past few years, TikTok arose as the undisputed champ of ...

[导读]传感器的DATA口需要接4.7K的上拉电阻。上拉电阻的作用是在单片机不进行输出以及传感器待机时，使得DATA口为高电平 ...

温度和湿度测量通常在家庭自动化、环境监测、气象站等许多应用中很有用。LM35旁边最常用的温度传感器是 DHT11，我们之前通过与Arduino和Raspberry连接构建了许多DHT11 项目Pi和许多其他开发板。在本文中，我们将学习如何将此DHT11 与 PIC16F87A连接，这是一个 8 位 PIC ...
