| :name: SHT3XD humidity sensor |
| :relevant-api: sensor_interface |
| |
| Get temperature and humidity from a SHT3XD sensor (polling & trigger mode). |
| |
| Description |
| *********** |
| |
| This sample application periodically (2 Hz) measures the ambient |
| temperature and humidity. The result is written to the console. |
| Optionally, it also shows how to use the upper threshold triggers. |

| Wiring |
| ******* |
| |
| This sample uses the SHT3X_DIS sensor controlled using the I2C interface. |
| Connect Supply: **VDD**, **GND** and Interface: **SDA**, **SCL** |
| and optionally connect the **ALERT** to a interrupt capable GPIO. |
| The supply voltage can be in the 2.15V to 5.5V range. |
| Depending on the baseboard used, the **SDA** and **SCL** lines require Pull-Up |
| resistors. |
| |
| Building and Running |
| ******************** |
| |
| This project outputs sensor data to the console. It requires a SHT3XD |
| sensor. It should work with any platform featuring a I2C peripheral |
| interface. It does not work on QEMU. In this example below the |
| :zephyr:board:`nrf51_ble400` board is used. |
