DS18S20是一种典型的1-Wire总线接口温度传感器，由Dallas Semiconductor公司生产。DS18S20数字温度传感器提供了9位高精度的摄氏温度测量，同时具有非易失性、用户可编程上下触发门限的报警功能。由于其独特的1-Wire总线接口，使得其可以占用极少的I/O引脚资源，使用起来十分方便-DS18S20 is a typical 1-Wire bus interface, temperature sensor, manufactured by Dallas Semiconductor. DS18S20 digital temperature sensor provides high-precision 9 Celsius temperature measurement, both non-volatile, user-programmable upper and lower trigger threshold alarm. Because of its unique 1-Wire bus interface, making it can take up very little I/O pin resources, is very convenient to use
