.. _ti_hdc_sample:
TI_HDC Sample
##############
Description
***********
This sample application periodically takes Temperature and Humidity
using the ti_hdc sensor driver. The result is written to the console.
Requirements
************
This sample needs a compatible sensor like HDC1010 or HDC1080
connected to the target board's I2C connector.
Example Breakout Boards:
* Pmod HYGRO: Humidity and Temperature Sensor Breakout board
Wiring
******
This sample is tested with the STM32L496ZG nucleo and the Pmod HYGRO
Temp/RH breakout board.
The sensor operates at 3.3V and uses I2C to communicate with the board.
External Wires:
* Breakout **GND** pin <--> Nucleo **GND** pin
* Breakout **VCC** pin <--> Nucleo **3V3** pin
* Breakout **SDA** pin <--> Nucleo **CN7-D14** pin
* Breakout **SCL** pin <--> Nucleo **CN7-D15** pin
Building and Running
********************
This sample builds one application for the HDC1080 sensor.
