溫度控制器
指導老師:何天讚   組長:陳彥廷   組員:賴志桓
本專題功能是利用溫度感測元件ADC0804感測到架構內部溫度,經8051 轉換
溫度值,在七段顯示器中顯示溫度,再利用程式控制,設定恆溫溫度,感測到
的溫度則會與所設定的溫度上下限值做比較,低於下限值,啟動電熱片開始加熱
且關閉風扇,高於上限值,啟動風扇開始降溫且關閉電熱片。恆溫時電燈發亮,
停止風扇與電熱片,使維持恆定的溫度。
Through using 8051, we are able to transfer the measured temperature, sensed by component ADC0804, into specific voltage values. Then, the temperature values are shown on the 74LS47 display. The operation temperature is also set to compare with a range of temperature limit. When the temperature is lower than the set point of low limit, the heating fan would automatically start. In the other hand, when the
temperature is higher than the up limit, the cooling fan will start to work and shut down the heater. When the temperature reaches the set point, the thermostat would light up and shut down all fans to maintain the constant temperature.
我們決定將壓電陶瓷晶片和鞋子做結合。
