The DS18B20 is a digital temperature sensor from DALLAS USA. It can be used to quantify the environmental temperature testing.
The sensor reads temperature range -55 ~ +125 ℃, with inherent temperature resolution of 0.5 ℃ and 9-12 bit serial output
Multi-point networking mesh temperature measurement can be achieved by deploying DS18B20 sensors on three lines.
This sensor can be directly plug and play with our IO expansion shield.
