Breakout board for the Sensirion SHT31-DIS-F with a built-in permeable membrane filter. This sensor is an extremely accurate digital (I2C interface) temperature and humidity sensing device, with +/-0.2°C temperature and +/-2% humidity accuracy typical. These specs far exceed the accuracy of ICs that came before it, including the HTU2x and SHT1x series, and improves upon the success of the SHT2x that came before it. In addition, the SHT31-DIS-B has a wide input voltage range of 2.4V-5.5V and includes temperature isolation and airflow cutouts as recommended for the optimal operation. Finally, in the case of environmental changes that could cause light condensation, the SHT31-DIS-B has a built-in heater to burn off any condensate.

This breakout includes a filter membrane to protect against environmental factors such as dust, water immersion and other particle ingress. This makes it perfect for harsher environments in which most other humidity sensors would fail.

As always, we have example code libraries available for this IC (Arduino platform), which can be found on our Github page (See Link Below)
