Easy to use temperature sensor for Arduino. it is powered by 1.4 V to 3.6 V. It communicates via the I2C bus, it has built-in pull-up resistors of 4.7 k Ω . The sensor measures the temperature with an accuracy of up to 0.5 °C with a resolution of 0.0625 °C.

The product is compatible with Arduino

The manufacturer providessample codealong with the connection scheme for users ofArduino.


Due to the fact that the maximum voltage with which the system works, is 3.4 V, to work with Arduino, necessary is a voltage converter. The exceptions are the modules operating with the voltages of 3.3 V, for example,Arduino Pro Mini 328 - 3.3 V/8 MHz.


  • Supply voltage: from 1.4 V to 3.6 V
  • Measuring range: -40 °C to 125 °C
  • Resolution:0,0625°C, 12-bit
  • Accuracy: +/- 0,5 °C in the range from -25 °C to 85 °C
  • Communication interface: I2C (TWI)



The system has 6 pins in the form of holes for self-soldering of the goldpin strap, pitch of 2.54 mm (not included in package, sold separately).
