One Wire Digital Temperature Sensor - DS18B20

SKU : OWDTS-DS18B20

This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus. This is a wonderful part that is the corner stone of many data-logging and temperature control projects.

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
