44、simple structure, convenient installment, low loss and wide range of temperature test, DS18B20 temperature test sensors are applied to the fields which needs the multipoint temperature test, such as the chemical industry, the grain, the environment supervision and so on. Because of the adoption of o

45、ne bus in the DS18B20 multipoint temperature test system, all DS18B20 are hung on one bus, and then the temperature conversion value of each test point is read by turns. As the conversion value must be read after reading-pin state for 8 times, and position and store data must be moved, so time spend

46、 much in reading one point of the data system by every time. If the temperature test system is large-scaled, the system loss caused by it is rather much, and then the alternate test speed of the system decreases obviously, which influences the efficiency of the multipoint temperature test system ser
