Raspberry Pi and Qwiic SHT31 sensor Demo

Posted by AlexChu, 11/12/2019

This is a demo to show you how to make raspberry Pi board work with Qwiic module (SHT31 temperature and humidity sensor).

Prepare hardwares:

Step 1 Setup the Raspberry Pi

Check out this super quick video on how to setup the Raspberry Pi.

 

Step 2 Connect

Connect the Zio development board with SHT31 Temperature & Humidity Sensor to the Raspberry Pi via the ZIO QWIIC HAT.

 

Step 3 enable the I2C bus
Either from the Raspberry Pi’s desktop or via SSH, Open the terminal and type in:
sudo raspi-config and press enter.

 

Using your keyboards arrow keys, select ‘5 Interfacing Options’ and press enter.
 


Scroll down to ‘P5 I2C’ and press enter.

 

 
Then select ‘<Yes>’ and press enter to enable the I2C interface for the ZIO QWIIC ecosystem.
 


Select ‘<Ok>’ and ‘<Finish>’ to return to the terminal.

 


Step 3 Download python script
Whilst still in the terminal type:
sudo git clone https://github.com/machineshopuk/SHT31
 


This will generate a folder called SHT31, enter it by typing:
cd SHT31

 


Then run the script by typing:
python SHT31.py
 


The script will output temperature and humidity values to the terminal.
