Bus line and the unique economic characteristics, so that users can easily set up sensor networks, the measurement system for the Construction of the introduction of new concepts. DS18B20 can set up procedures for 9 to 12 of resolution, accuracy to ± 0.5 ° C, built AD converter. We are using a MCU and 18 B20 bus communication, and then collected by the MCU to the temperature signal, given to the display device display. When the temperature is above 40 degrees, or below 10 degrees, hot or cold alarm.
