DS18B20 - 1Wire Digital Thermometer

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 Specifications:- Voltage Range on Any Pin Relative to Ground : -0.5V to +6.0V Storage Temperature Range : -55°C to +125°C Operating Temperature Range : -55°C to +125°C Package Includes:- 1 x DS18B20 - 1Wire Digital Thermometer
