温湿度传感器SHTxx的驱动程序；主要是采用盛世瑞恩的芯片；精度高。-Temperature and humidity sensors SHTxx driver mainly by Prime Ryan chips precision.

简易智能迷宫小车的控制系统以STC89C52为核心，用一片L298N驱动两个减速电机。12V电源单独给电机供电，再用7805把12V电源降压至7V给单片机供电。小车的传感器模块感应壁障，并将壁障信号输入最小系统版，最小系统版根据程序设计的要求做出相应的判断送给电机驱动模块，让小车来实现前进、左转、右转、反转等基本功能。-Simple intelligent control system of the labyrinth car STC89C52 as the core, two geare

电机的驱动程序，由传统的机械限位开关改为红外传感器来控制电机的停止与转动，提高控制效率及限位开关的寿命-Motor driver, from traditional mechanical limit switches to infrared sensors to control the rotation of the motor is stopped, improve control efficiency and lifetime limit switch

用在树莓派的Windows 10 IoT系统的控制温湿度传感器的程序， 主体用C#写的，DHT11的驱动引用了一个C++文件。(A program for controlling temperature and humidity sensors used in raspberry pie Windows 10 IoT systems. The main body is written in C#, and the DHT11 driver refers to a C++ file.)
