Description

The DS18B20 is a very popular temperature sensor due to its simple wiring, wide temperature range, and accuracy across a wide temperature range. The sensor uses a 1-wire digital protocol and features a unique 64-bit ID burned into each sensor a the factory, meaning multiple sensors can share one digital input pin on a microcontroller / single board computer.

The sensor is fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. This version is a bare sensor, and should not be directly exposed to the elements, but we do offer a weatherproof/waterproof version as well.

The sensor can operate on voltages between 3.0 and 5.5VDC and is compatible with 3.3 and 5V logic systems. A 4.7K pull-up resistor is required on the data line to keep the data transfer stable and is included with the sensor.

Features

  • Usable temperature range: -55 to 125°C (-67°F to +257°F)
  • Uses 1-Wire interface- requires only one digital pin for communication
  • Multiple sensors can share one pin
  • Temperature-limit alarm system
  • ±0.5°C Accuracy from -10°C to +85°C
  • Query time is less than 750ms
  • 1 Wire Temperature Sensor
  • 9 to 12 bit selectable resolution

Package Contents

  • 1 x DS18B20 Temperature Sensor
