Do you want to build a simple and high-precision digital weather station, or learn to control the weather in the house? This sensor will tell you when you need to turn off your air conditioner or run a humidifier in the greenhouse.

The heart of this temperature and humidity sensor is the SHT31 chip by Sensirion.

The chip is made using patented CMOSens® technology, calibrated and characterized with high measurement accuracy.


The module has two groups of Troyka contacts exposed:

Bottom group

  • Power (V) - connect to the operating voltage on the microcontroller
  • Ground (G) - connect to the GND pin on the microcontroller

Top group

  • Alarm (D) - I²C bus data pin. Connect to the SDA pin on the microcontroller
  • Signal (C) - Clock pin for the I²C bus. Connect to the SCL pin on the microcontroller

When connecting to an Arduino or Iskra, try using a Troyka Shield. If you want to forget about complex wiring, try the Troyka Slot Shield.


At the hardware level, the sensor communicates with the control electronics via I²C.

No need to worry about bits and bytes. We have written libraries that hide the complexity and details of the protocol. In all, the communication with the module is only a little more complicated than blinking an LED.
