Description: 本文介绍了基于DS18B20单线数字温度传感器的电子孵化器的设计实现。设计中基本涵盖了对单线数字温度传感器DS18B20的原理的运用。在电子孵化器的制作过程中,硬件电路由单线数字温度传感器DS18B20和继电器的连接,电路可以把温度转化成数字用LED数码显示器显示输出。本设计采用外部供电方式(即用吹风机加热)。单线数字温度传感器DS18B20的温度测量范围从—55℃到+125℃,我们在设计中要求温度的范围是30℃到35℃(即温度下限为30℃,上限为35℃),温度低于30℃或者温度高于35℃,继电器自动断电,系统就会自动进行加热,以使温度控制在30℃到35℃之间。利用这个原理来实现电子孵化器。-err
