DS 18B20 Digital Temperature Sensor. Component Guide 9

DS-18B-20 DS 18B20 is a Programmable Digital Temperature sensor that gives Digital outputs based on the temperature. It provides 9-12 configurable Bit temperature readings which indicate the temperature of the device. Information is sent to / from to connect from a Central Microprocessor to the DS 18B20. Power for reading, writing and temperature conversion can be derived from the Data line itself so that no external power source is needed.

DS 18B20 contains a unique serial number, multiple DS 18B20 s can exist on the same 1 – Wire bus.This helps to connect many temperature sensors in different places. It can be powered from the data line itself. Power supply range is 3.0V to 5.5 V. It measures temperatures from -55 Degree C to + 125 Degree C. It converts 12- bit temperature to Digital word in 750 ( Max ).

Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system etc.
