摘要
系统以单片机为控制核心,以超声波液位传感器以及数字温度传感器DS18B20实现水位及温度信号的采集,采用增量式PID控制算法实现水温的自动控制,使水温保持在设定温度的上下1℃范围内。
The MCU is used as control core in this system,the ultrasonic liquid level sensor and digital temperature sensor DS18B20 are used for collecting signals of water level and temperature.It adopted the incremental PID control algorithm for the realization of automatic control for water temperature and made the water temperature keep in 1~C scope of the set temperature.
