摘要
恒温箱有着广泛的应用,其关键技术为保持箱内温度的恒定,本文采用AT89C52单片机和DS18B20数字温度传感器测量恒温箱的温度,并和设定温度比较。根据比较的结果控制加热电阻和电风扇的动作与否,从而达到控制温度恒定的目的。
Incubators have a wide range of applications, its key technology is to control a constant temperature inside, this paper uses AT89C52 SCM and DS18B20 digital temperature sensor to measure the temperature of the incubator, then compared with the set temperature . According to the results of this comparison, we control of the heating resistor and the fans, so as to,achieve the purpose of constant temperature control.
