Module with digital temperature sensor TMP102 with I2C communication interface (TWI). Conclusions are popular goldpin connectors, to connect the sensor to the main unit (e.g., Raspberry Pi, STM32Discovery or Arduino) via wires.


The product is compatible with Arduino

The manufacturer provides sample code along with the connection scheme for users of Arduino.


Since the maximum voltage with which the system works, it's 3.4 V for Arduino needed a voltage Converter. Inyjątkiem are the modules operating 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
  • Accuracy: +/- 0,5 °C in the range from -25 °C to 85 °C
  • Resolution: 12-bitow ( 0,0625 °C)
  • Communication interface: I2C (TWI)
  • Two mounting holes


The set does not contain strap goldpin, it can be purchased separately.



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