Sensiron Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. The SHT31-D sensor has an excellent ±2% relative humidity and ±0.3°C accuracy for most uses.

This sensor has a true I2C interface, and two address options. It also is 3V or 5V compliant, so you can power and communicate with it using just about any microcontroller or microcomputer.

The breakout board contains the SHT31-D and some supporting circuitry such as pullup resistors and capacitors. Each order comes with one fully assembled and tested PCB breakout and a small piece of header. You'll need to solder the header onto the PCB but it's fairly easy and takes only a few minutes even for a beginner or we can do it for you, just choose the right variant.

Power Pins:
  • Vin - this is the power pin. The chip can use 2.5-5VDC for power. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like for Arduino, use 5V. For a 3.3V controller like a Raspbery Pi, connect to 3.3V
  • GND - common ground for power and logic
I2C Logic pins:
  • SCL - I2C clock pin, connect to your microcontrollers I2C clock line. This pin has a 10K pullup resistor to Vin
  • SDA - I2C data pin, connect to your microcontrollers I2C data line. This pin has a 10K pullup resistor to Vin
Other Pins:
  • ADR - This is the I2C address selection pin. This pin has a 10K pull down resistor to make the default I2C address 0x44. You can tie this pin to Vin to make the address 0x45
  • RST - Hardware reset pint. Has a 10K pullup on it to make the chip active by default. Connect to ground to do a hardware reset!
  • ALR - Alert/Interrupt output. You can set up the sensor to alert you when an event has occured. Check the datasheet for how you can set up the alerts
What is included in the SHT31-D sensor module package?
Each order includes one fully assembled and tested PCB breakout with the SHT31-D and a small header. You must solder the header onto the PCB, or choose a variant with the header already installed.
What voltages does the sensor support and how should I power it?
The chip supports 2.5 to 5 V DC supply. The board is compatible with 3 V or 5 V logic, so power and logic level should match your microcontroller.
How do I set the I2C address on this module?
The ADR pin selects the I2C address. The default address is 0x44 with a 10K pull down. Tying ADR to Vin selects 0x45.
What are the temperature and humidity accuracy specs?
The SHT31-D offers about 2 percent relative humidity accuracy and about 0.3 degrees Celsius accuracy for most uses.
Are there reset and alert features on the module?
The RST pin provides a hardware reset with a 10K pullup and can be grounded to reset. The ALR pin offers an alert output; check the datasheet for available alert configurations.
