【正文】 液晶顯示器LCD1602A 溫度傳感器DS18B20 步進(jìn)電機(jī)28BYJ48 英文摘要What we do can be achieved through the collection of temperature sensor indoor temperature to control motor rotation, so that the temperature be applied to some higher requirements in the temperature range of occasions, such as the placement of precision instruments use place. What we do can realize the function of the temperature sensor, the temperature measurement range of 0 to 100 degrees Celsius, the accuracy of degrees Celsius, and temperature measurements of realtime display on the measurement range in when the temperature rise to 25 degrees Celsius and above, the stepper motor clockwise beginning。When the temperature below 10 degrees Celsius, the stepper motor begins to rotate counterclockwise. I made as a result, liquid crystal display, can return to the realtime display temperature sensor value, and when the temperature sensor returned value to meet the corresponding requirement of the motor rotation or stop the motor rotation or stop.Key words: microcontroller STC89C52 LCD1602A temperature sensor DS18B20 stepper motor 28 byj 48三、引言溫度是表征物體冷熱程度的物理量，是工農(nóng)業(yè)生產(chǎn)過程中一個(gè)很重要而普遍的測(cè)量參數(shù)。由于溫度測(cè)量的普遍性，溫度傳感器的數(shù)量在各種傳感器中居首位，約占50%。有著廣泛的應(yīng)用價(jià)值與寬闊的市場(chǎng)前景。四、硬件設(shè)計(jì)設(shè)計(jì)的總體電路圖如下：在給設(shè)計(jì)中，采用STC89C52芯片作為主控制芯片，通過編寫程序下載到主芯片里面對(duì)各個(gè)部件進(jìn)行控制。下面，將詳細(xì)介紹各個(gè)部件模塊的功能和作用。注：引腳功能前加“”，說明其是低電平有效。溫度傳感器DS18B20：以下是溫度傳感器DS18B20模塊的電路圖：溫度傳感器D
