SHT31 SMART GADGET: BLE Temperature & Humidity Sensor with LCD Display


The SHT31 Smart Gadget is a reference design circuit board which demonstrates the outstanding performance and ease of use of Sensirion's humidity and temperature sensors. It not only shows humidity and temperature values on the display, but it can also communicate wirelessly with a Bluetooth Smart capable device like a smartphone.

SHT31-DIS is the next generation of Sensirion's temperature and humidity sensors. Its functionality includes enhanced signal processing, two distinctive and user selectable I2C addresses and communication speeds of up to 1 MHz. The DFN package has a footprint of 2.5 x 2.5 mm^2 while keeping a height of 0.9 mm. This allows for integration of the SHT31-DIS into a great variety of applications. Additionally, the wide supply voltage range of 2.15 V to 5.5 V guarantees compatibility with diverse assembly situations.

For developers, full design resources of the SHT31 Smart Gadget are available on GitHub.
