Digital Temperature Sensor Board

This easy-to-use temperature sensor mini module gives a digital output signal and allows easy interfacing to a microcontroller or microprocessor such as an Arduino or Raspberry Pi using the 1-Wire® communication protocol. Being digital, the sensor board can be placed a distance from the controller circuit with interference from its surroundings. Using three methods of connection, 5V positive power supply (red wire), GND negative power supply (black wire), and a bidirectional data line for temperature output and data request (yellow wire), the Digital Temperature Sensor Board can measure temperatures ranging from -55°C to 125°C.


  • converts temperature to a digital bit stream signal
  • Capable of expressing temperatures with decimals
  • ±0.5°C accuracy in the -10°C to 85°C range
  • suitable for Arduino®


  • measurement range: between -55 °C and 125 °C / -67 and +257 °F
  • power supply: 5 VDC
  • measurement resolution: 9 to 12 bits - User Definable
  • dimensions: 22 x 22 x 5 mm / ca. 0.87 x 0.2 inch (L x W x H)
  • protocol: 1-Wire®
