Product Description：
This is the latest DS18B20 digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus. This is a wonderful part that is the corner stone of many data-logging and temperature control projects.
DS18B20 is a waterproof temperature sensor packed in a metal and waterproof housing. For communication with Croduino/Arduino, it uses only one wire and it is possible to put up to 127 sensors on one code and measure temperature in 127 different places by using just one wire!
