本报告介绍了基于AT89S52单片机为核心的、以AD0809数模转换芯片采样、以1602液晶屏显示的具有电压测量功能的具有一定精度的数字电压表。在实现基础功能要求之上扩展了串口通讯、时钟功能、高压报警、短路测试、电阻测量、交流电压峰峰值和周期测试等功能，使系统达到了良好的设计效果和要求。( This report describes on AT89S52 microcontroller as the core, to AD0809 DAC chip sampling, digital voltmeter with a certain precision voltage measurement function has LCD display with 1602. On the basis of the functional requirements to achieve extended serial communication, clock function, high pressure alarm, short circuit testing, resistance measurement, AC voltage peak value and cycle testing and other functions, allowing the system to achieve a good performance and design requirements. )

温度传感器数据采集程序，并在数码管上显示。(The temperature sensor data acquisition program is displayed on the digital tube.)

说明：  对stm32f407xx使用的烟雾传感器模块MQ2的例程，使用的亦为模拟引脚读取功能(For the routine of the smoke sensor module MQ2 used in stm32f407xx, the analog pin reading function is also used.)

说明：  SJA1000收发程序,KEIL平台，C语言开发。(SJA1000 transceiver, Keil platform, C language development.)

温度仪表通用程序，可检测热电偶和CU50。程序带有PID控制算法和PID参数自整定算法。(General procedure can detect the temperature meter, thermocouple and CU50. The program with a PID control algorithm and the PID parameters self-tuning algorithm. )

说明：  MPU6050传感器的六轴姿态解算算法代码(Six-Axis Attitude Solution Algorithmic Code for MPU6050 Sensor)

基于51单片机温度传感器源码，经试验验证OK的。(Based on 51 single-chip temperature sensor source code, the test verified OK.)

读取DS18B20进行温度测量以后的结果并在1602液晶上显示。 基于DS18B20的温度控制器。温度控制范围在20~30℃，当温度大于30度时，停止加热，小风扇通电开始降温，绿灯亮。温度低于20度时，小风扇停止通电，开始加热。红灯亮。全过程有LCD数字温度显示。(Read DS18B20 temperature measurement after the results of the 1602 LCD display. Based on DS18B20 temperature controller. Temperature control range of 20 to 30 ℃, when the temperature is greater than 30 degrees, stop heating, small fan is energized to start cooling the green light. When the temperature is below 20 degrees, a small fan is stopped is energized, the heating is started. Red light. The whole process of LCD digital temperature display.)

说明：  最简单的读取AD值的程序。初始化时调用初始化程序，运行过程中，可以定时读取AD值。可以用做温度检测或者电压检测。(The simplest program to read AD values. Initialization call initialization program, running process, can read AD value at regular intervals. It can be used for temperature detection or voltage detection.)
