Principle
DS18B20 module is using a single bus. The power supply voltage range of 3.0 V to 5.5 V and
no standby power supply. It can Measuretemperaturerangefor-55degreeto+125degree
with accuracy of+/-0.5°C.
The programmable DPI of temperature sensor is From 9 to 12. temperature conversion is 12
digits lattice type. maximum is 750 milliseconds. Families can be defined non-volatile
temperature alarm Settings.
Each DS18B20 contains a unique serial number so that multiple ds18b20 scan exist in a bus.
