DS18B20 Digital Thermometer

1198

The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile  user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range  of  -55°C  to  +125°C  and  is  accurate  to ±0.5°C  over  the range  of  -10°C  to  +85°C.  In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply.

Description

Description: 

The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile  user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range  of  -55°C  to  +125°C  and  is  accurate  to ±0.5°C  over  the range  of  -10°C  to  +85°C.  In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply. 

Each  DS18B20 has a unique 64-bit serial code, which  allows  multiple  DS18B20s  to  function  on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control  many DS18B20s distributed over a large area.  

Features:

Unique 1-Wire® interface requires only one port pin for communication

Each device has a unique 64-bit serial code stored in an onboard ROM

Multidrop capability simplifies distributed temperature sensing applications

Requires no external components

Can be powered from data line. Power supply range is 3.0V to 5.5V

Measures temperatures from –55°C to +125°C (–67°F to +257°F)

±0.5°C accuracy from –10°C to +85°C

Thermometer resolution is user-selectable from 9 to 12 bits

Converts temperature to 12-bit digital word in 750ms (max.)

User-definable nonvolatile (NV) alarm settings

Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition)

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