DS18B20 is a digital temperature sensor which is from DALLAS U.S. It can be used to quantify the environmental temperature testing. is manufactured DALLAS U.S.
The temperature range -55 ~ +125 , the inherent temperature resolution of 0.5 , support multi-point networking mesh. Three DS18B20 can deloyed on three lines, to achieve multi-point temperature measurement. It has a 9-12 bit serial output.
