用一只精密集成温度传感器LM35,一只100K 固定电阻和一只3(1/2)。位液晶显示数字面板表就可以组成一台测温范围-55℃～+150℃的摄氏温标数字温度计,不需作任何调整和标定,即可达到室温下±1/4℃,全量程±3/4℃的测温精度,分辨力则为±0.1℃。LM35是国家半导体公司生产的精密集成温度传
Use a precision integrated temperature sensor LM35, a 100K fixed resistance and a 3 (1/2). Bit LCD digital panel meter can form a temperature range of -55 ℃ ~ + 150 ℃ Celsius temperature scale digital thermometer, without any adjustment and calibration, you can reach ± 1/4 ℃ at room temperature, full scale ± 3 / 4 ℃ temperature measurement accuracy, resolution is ± 0.1 ℃. The LM35 is a precision integrated temperature transmitter from National Semiconductor
