temperature. Can train students to improve it to make to originally design with programming ability to the interest that the one-chip computer studies. Adopt USB mouth to supply power, can meet USB adapter USB mouth of circuit boards of people or connect the computer USB port directly. In this way, not only save resources but also can obtain comparatively ideal working voltage. USB oral appearance and power port define that is shown as in Fig. 3.

Reading and writing sequence of DS18B20 and temperature measurement principle is the same as DS1820, figures of the temperature value just got are different, the time delay time that and the...
