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
|
|
