电商毕设小项目，希望对新手能有所帮助，高手就别下载了(simple project)

介绍了一种pt100温度传感器的测量电路，包括前段的传感器电路和单片机信号调理电路。(A pt100 temperature sensor measurement circuit, including front-end sensor circuit and single-chip signal conditioning circuitry.)

真空机组先启动SK-30水环真空泵带压力降到6.5 KPa（此时真空机组的抽速是SK-30的抽速）启动ZJP-1200（此时真空机组的抽速是ZJP-1200抽速）待压力降到4 KPa启动ZJP2500（此时真空机组的抽速是ZJP-2500抽速）待压力降到1kpa时最后启动ZJP5000（此时真空机组的抽速是ZJP-5000抽速）到100Pa达到使用真空度时时就可以关闭机组(Vacuum unit first start SK-30 water ring vacuum pump with pressure drops below 6.5 KPa (pumping speed of the vacuum unit at this time is SK-30 pumping speed) start ZJP-1200 (pumping speed of the vacuum unit at this time is ZJP-1200 pumping speed ) until pressure drops below 4 KPa start ZJP2500 (pumping speed of the vacuum unit at this time is ZJP-2500 pumping speed) until the last start when pressure drops 1kpa ZJP5000 (pumping speed of the vacuum unit at this time is ZJP-5000 pumping speed) to 100Pa achieved using vacuum unit can be closed from time to time)

MSP430低功耗，用霍尔元件触发，功耗极低(MSP430 low power consumption, are triggered by Holzer components, low power consumption)

VB 开发C51的动态链接库，可以拿来直接用的，(VB-C51 dynamic link library that can be used directly, and)

基于STM32的平衡小车源码(精简入门版)，可实现小车的直立平衡。(Balanced car source code based on STM32 (streamlined entry version) can achieve vertical balance of the car.)

1621-833-01.ASM的测试程序源代码(1621-833-01.ASM test procedures for source code)

单片机与上微机通信的汇编语言程序 支持485传输协议，软件用modbus协议编写(SCM and computer communications on the assembly language support, 485 transmission agreement Software modbus connection with the preparation of the agreement)

说明：  正弦波的显示 ，示波器，keil5正弦波的显示 ，用于测试波形的产生(Sine wave display, oscilloscope, keil 5 sine wave display, used to test the generation of waveforms)

该程序实现门锁开关报警功能，电路图包括51单片机、DS12887时钟芯片、LCD显示(The program to achieve lock switch alarm, circuit diagrams, including 51 single, DS12887 clock chips, LCD display)
