基于PIC单片机的数据采集系统，通过DS18b20将采集到的温度用串口调试助手 传送到上位机-PIC Microcontroller based data acquisition system will be collected by DS18b20 temperature with serial debugging aids sent to the host computer

用PIC中档单片机集成的A/D模块，采集LM35输出的模拟温度值，采样速度为2Hz。然后将10位的A/D转换结果分为高低两个字节（高字节8位、低字节2位），通过USART模块的异步模式传到PC机上。通信方式设定为波特率9600、帧格式为8位数据位、无校验位、1位停止位。-Integrated with a mid-range PIC microcontroller A/D module, collecting the the LM35 output of analog temperature v

The present paper describes the design of a cost effective, better resolution data acquisition system (DAS) which is compatible to most of the PC and laptops. A low cost DAS has been designed using PIC12F675 having 4-channel analog input with 10-
