Description

The DS18B20 digital thermometer measures temperatures from 9 to 12 bits in Celsius and features an alert function with nonvolatile user-programmable higher and lower trigger points. The DS18B20 connects with a central CPU through a 1-Wire bus, which by definition requires just one data line (and ground). Furthermore, the DS18B20 may draw power directly from the data line (parasitic power), removing the need for an additional power supply.

DS18B20 Temperature Sensor Module typically requires an external 10K pull-up resistor on the output pin for proper communication between the sensor and the Arduino. However, because the module already includes a pull-up resistor, you do not need to add one.

APPLICATION

  • Thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system.

FEATURES

  • The 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
  • Thermometer resolution is user-selectable from 9 to 12 bits
  • Converts temperature to the 12-bit digital word in 750ms (max.)
  • User-definable nonvolatile (NV) alarm settings
  • The alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition)
  • Board DS18B20 chip DS18B20 chip left 3P round hole seat is easily accessible at the same time
  • Chip pin all leads, built-in pull-up resistor
  • On-board power indicator
