10This sample application periodically (2 Hz) measures the ambient
11temperature and humidity. The result is written to the console.
12Optionally, it also shows how to use the upper threshold triggers.

20*******
21
22This sample uses the SHT3X_DIS sensor controlled using the I2C interface.
23Connect Supply: **VDD**, **GND** and Interface: **SDA**, **SCL**
24and optionally connect the **ALERT** to a interrupt capable GPIO.
25The supply voltage can be in the 2.15V to 5.5V range.
26Depending on the baseboard used, the **SDA** and **SCL** lines require Pull-Up
27resistors.

29Building and Running
30********************
31
32This project outputs sensor data to the console. It requires a SHT3XD
33sensor. It should work with any platform featuring a I2C peripheral
34interface.  It does not work on QEMU.  In this example below the
35:zephyr:board:`nrf51_ble400` board is used.
