DS18B20is 1-wire digital temperature sensor from Maxim IC suitable with 9 to12 bit precision over the range of operation (-55°C to 125°C) .

With an accuracy of ±0.5°C over the range of -10°C to +85° and multiple data logging of temperature spread in wide area network, connected in single data bus, DS18B20 comes handy as it has been assigned unique 64-Bit Serial Number, thus a single microcontroller can receive data from 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:-

• Thermostatic Controls
• Industrial Systems
• Consumer Products
• Thermometers
• Thermally Sensitive Systems
