DS18B20

  • Used in 1 wire network temperature measurement system for temperature measurement
  • Probe length: 1 m
  • Built-in chip: DS18B20
  • The new “first-line device” BS18B20 is smaller in volume, wider in applicable voltage, and more economical
  • Dallas Semiconductor’s digital temperature sensor DS1820 supports temperature sensing of the “first-line bus” interface
  • Machine. The unique and economical characteristics of the first-line bus make it easy for users to form sensor networks and introduce a new concept for the construction of measurement systems.
  • Now, the new generation of “DS18B20” is smaller, more economical, and more flexible. This allows you to give full play to the strengths of the “first-line bus.”
  • The following is a detailed application of DS1820
  • characteristics
  • • Unique single-line interface requires only one port pin for communication
  • • Simple multi-point distribution application
  • • No need for external devices
  • Electricity available through data lines
  • • Zero standby power consumption
  • • Temperature range -55 ~ +125 °C, increasing at 0.5 °C. Fahrenheit Devices-67 ~ +2570F, increasing by 0.90 F
  • • Temperature read in 9-digit quantities
  • • Temperature digital quantity conversion time 200ms(typical value)
  • Non-volatile temperature alarm settings that users can define
  • Alarm Search Command identifies and marks devices that exceed the programmed temperature limit(temperature warning conditions)
  • Applications include temperature control, industrial systems, consumer products, thermometers, or any thermal sensing systems.
