摘要
为了使温度保持在某一范围,利用温度传感器DS18B20的特点,与AT89S52单片机构成实时温度监测系统,通过红外遥控进行温度上下限的参数设置,并通过LCD1602液晶显示相关数据。当温度超过上下限时,进行报警,通过控制继电器的通断控制加热,并通过LN298控制风扇转动进行降温,使温度控制在设定的范围之内,较好地实现了温度的监控。
The upper and lower limits in the temperature were set by infrared remote control to keep the temperature within a certain range ,which constituted a real-time temperature monitoring system with the mierocontroller AT89S52 with Temperature sensor DS18B20, then data was shown on LCD1602 screen. System would alarm when the temperature exceeds the upper and lower limit, then it will be heated by control relay switching and cooling by fan that controlled by LN298 so that temperature will be con- trolled winthin the limits set for realizing temperature monitoring.
